Actor Robbie Amell is joining the cast of superhero TV series The Flash as one half of DC Comics duo Firestorm.
The star will portray maintenance worker Ronnie Raymond, who plays a key role in transforming Grant Gustin's character Barry Allen into The Flash.
In the comics, Raymond is involved in a nuclear accident with physicist Martin Stein which allows them to fuse together to create the superhero Firestorm.
The role in the Arrow spin-off reunites Amell with his The Tomorrow People producer Greg Berlanti, according to The Hollywood Reporter.
Amell says, "I'm so excited to join forces with Greg Berlanti and The CW (U.S. TV network) again on The Flash. Being brought into the DC Universe is a dream, I can't wait to get started!"
The Flash will premiere in October (14).
