Get ready to welcome Tom Felton back to your TV screen because he has just landed a new role.

Tom is joining The Flash and will play a detective named Julian Dorn.

For those of you who aren't familiar with The Flash, it's a take on the DC Comic under the same name.

It sees the main character, Barry Allen (played by Grant Gustin – who you might remember from 90210), witness his mother's murder when he was a young child. His father was wrongly convicted of the crime and sent to prison.

Barry becomes a socially awkward crime scene investigator for the Central City Police Department, however, he can never escape his tragic past.

Fourteen years after his mother's death, Central City is hit with a vicious thunder storm and Barry is struck by lightning and doused with chemicals in his lab.

After he wakes up from a 9-month coma, he discovers he's able to move at superhuman speed. He vows to protect his city and his father with his new powers, but ultimately keeps it a secret from everyone else.

Now, in the third season, a new police detective comes in, Julian Dorn (Tom Felton) and he begins to question Barry's good-guy nature.

We love that Tom is going back to his bad boy roots, and we can see a whole lot of drama happening with his character.

We'll defo be tuning into this one!
