"Welcome back to Hogwarts," the teaser wrote, with a yellow background and wizard at the ready.
Harry Potter And The Cursed Child premiered in London's West End in July 2016 and proved to be a huge success.
The play's story picks up 19 years after the events of Harry Potter and The Deathly Hallows, and features Harry Potter as a senior figure at the Ministry of Magic while his son Albus Severus Potter is set to start at Hogwarts.
The book's owner was an extra in the film, and was the first person to request his signature. Emma Watson and Rupert Grint also signed the book, which was auctioned by Teesside-based Vectis.
Vectis claim the book's owner asked the actor to sign the now-iconic novel as he sat in a marquee on set at Goathland on the first day of filming. The North Yorkshire village appears in the film as Hogsmeade.
He wrote on Verity Collins' novel: "To Verity, best wishes Daniel Radcliffe."
The actor who portrayed Hagrid in the franchise, Robbie Coltrane, also wrote his autograph on the novel while the film's director, Chris Columbus, wrote "Believe in magic".
The novel's owner, Verity Collins, was having chemotherapy to treat leukaemia. Collins' mother, Valerie Rudd, is selling the book on her behalf.
Rudd, who is selling the book on Verity's behalf, said: "She loved her time there. We would have even paid for her to be an extra. She was a big fan of the books.
“When Verity was 13 she was spending lots of time in the hospital and she’d read the books while she was there. I started reading the first one in the hospital with her."
Her mother continued explaining the story of Verity's part in the movie;
"So when we found out they were advertising for extras for the film we applied straight away, and even though she was having her treatment she was allowed to do it.
“She was about 15 at the time and he would have been about 11. She was with a group of extras, saw Daniel Radcliffe sitting by himself and felt sorry for him so she went and talked to him," Rudd continued.
The book, which has 13 signatures, was the first item Radcliffe had ever been asked to sign; "He said it was the first time anyone had asked him for an autograph."
Kathy Taylor, a representative from Vectis, said the book had smashed its "conservative" €500 estimate; "It's such a lovely story. It's always difficult to gauge the price when something is unique."
"The seller, who now lives in the south, has great memories of her time on the film and the way the cast treated her during a difficult time while she was ill but her mum said recently it had been sitting in a drawer," she added.
"It became apparent when we promoted the sale on social media it was likely to have been signed on the first day of filming on what was the first Harry Potter film, with actor Chris Rankin, who played Percy Weasley, confirming he had signed the book as well."
When it comes to dating, finding someone with similar interests to you can often be hugely important. Especially when those interests include magical worlds, fantastic creatures and beasts, and cruel deaths.
Game of Thrones fans and Harry Potter lovers are often pretty…intense…when it comes to their appreciation of the world-famous novels and franchises. It makes sense that they'd have a lot in common.
A study has taken place at the University of Oklahoma, where researchers analysed over 400 readers (male and female) and measured their exposure to various fiction genres, and the results are vital for your fantasy-fuelled love lives.
The attitudes of the participants towards gender roles and sexual behaviour were also studied, and we are loving this form of science.
The readers were tested on their exposure to seven different genres- classics, contemporary literary fiction, romance, fantasy, science fiction, thriller, and horror. They were also asked for their views on a series of toxic beliefs about relationships.
These beliefs included quips such as: "disagreement is destructive", "mind-reading is expected", "romantic partners cannot change", "the sexes are different" and "the expectation of sexual perfection".
The respondents were told to explain to which degree they agreed or disagreed with the alternating statements. All in the name of love.
The study is called. 'What you read and what you believe: Genre exposure and beliefs about relationships' and was published in the Psychology of Aesthetics, Creativity, and the Arts journal.
The results found that people who had the most exposure to fantasy genres and sci-fi had the healthiest beliefs about how loving relationships should function.
We bet Dumbledore gave some decent wisdom about Tinder swiping.
Interestingly, readers who enjoyed fantasy and science fiction novels were "less likely to support the belief that disagreement is destructive". Fighting can be a healthy way to air grievances, even if it's with a wand or a sword…
Fans of the fantasy genre were also less likely to hold "the belief that partners cannot change, the belief that sexes are different, and the belief that mind-reading is expected in relationships".
Stephanie C. Stern led the research team at the University of Oklahoma, and wrote of their findings; "Individuals who scored higher for exposure to science fiction and fantasy were less likely to endorse four unrealistic relationship beliefs."
Even Jon Snow realised that having a fling with your aunt is a little too unorthodox for him, but Cersei and Jaime endorse the incest vibe.
Ron and Hermione bickered their way through the HP franchise, but made peace in the end with a big sloppy kiss after destroying a Horcrux. Seems like a good way to find love?
Many of us who grew up with the entire Harry Potter franchise remember waiting in those incredibly long queues for the latest book to be released, eagerly sprinted to the cinema for the flicks and desperately trying to dodge spoilers about character plots.
We also know that once it gets rebooted, we're officially OLD. Daniel Radcliffe will always be our Harry, Emma Watson our Hermione, and Rupert Grint our ginger nut Ron.
The actor who played the title role has now confirmed his thoughts that the hugely popular franchise will be rebooted, and we're totally in denial. Please don't do this to us.
Radcliffe spoke toIGNabout playing the boy wizard in the formative film series, sharing his affirmation that "some other version" of the movies will be created in the future.
"I’m sure there will be some other version of it. I know I’m not the last Harry Potter I’m gonna see in my lifetime – we’ve already got a few more in stage play Cursed Child."
The Fantastic Beasts franchise has kept the wizarding world alive (and is allegedly getting five films), as well as Pottermore and Harry Potter World. Radcliffe didn't rule out the possibility of a Harry Potter TV spin-off.
The actor recently revealed that the spin-off would be intriguing especially if it featured the Marauders- the name given to the group of friends featuring Harry's papa James Potter, Remus Lupin, Peter Pettigrew and Sirius Black.
The Marauders gang aren't alive before the final book or movie, the movie would presumably be a prequel. "I feel like there are other stories from that world that you could absolutely turn into a TV series, 100 percent," Daniel told TV Guide.
"A series with the older generation Marauders, that could be very cool." Amen, Daniel, Amen.
“To a certain extent with things like the play and Fantastic Beasts, I think people are still interested in talking to me about it, but nothing’s been happening in that area,” he told E! Newsin May of last year.
“At the moment, I’m very much enjoying playing lots of different stuff.” In an interview with The Hollywood Reporterhe wouldn’t mind reprising his role.
“I’m never going to close that door, but I think I’ll be happy enough and secure enough to let someone else play it,” he said at the time.
Radcliffe's latest role sees him take on the part of a low-level angel in Miracle Workers who must convince God to let humans survive.
Rupert Grint and Matthew Lewis are probably two of our all-time fave Harry Potter stars – and we kinda love them even more after hearing about the big prank Rupert has been playing on Matthew.
Matthew (or Neville Longbottom, as we like to still call him) revealed on Twitter last month that his former co-star had been putting food on his tab at his favourite restaurant for a number of months. Cheeky.
And when he was on This Morning today, he was asked to explain the whole incident:
"I saw Rupert for the first time in a few years and we were in Orlando and he told me he had been going to this restaurant, and I said: 'That's one of my favourite restaurants', and he's like, 'I know', and I said, 'How would you know that?' and he said, 'That's because I've been putting all my food on your tab for several months!' .. It could have gone on forever – I would never have known!"
Ah, how we wish Ron and Neville were still up to no good… Those were the days.
If you're a Harry Potter fan (who isn't), then you'll really wish you were at the Universal Orlando Resort right now.
The theme park hosted its third annual Harry Potter weekend celebration, and some of our favourite characters decided to pop by and surprise fans.
And what more could you ask for other than Ron and Ginny Weasley together.
Feeling nostalgic? We're loving this pic.
The actress, Bonnie Wright, shared a snap of the two ginger wizards and captioned it, "Family time."
Earlier in the weekend the HP alum also joined Matthew Lewis (Neville Longbottom),Katie Leung (Cho Chang) and Evanna Lynch (Luna Lovegood) for a panel that showed their favourite memories from the movies.
Ah, to be a kid and binge watch Harry Potter again.
