Everyone’s favorite Hollywood nice guy is about to go over to the dark side – if you can call a five-alarm fire dark.

Deadline is reporting that Brendon Fraser has joined the upcoming HBO Max film Batgirl as the main antagonist. Sources at Deadline say that Fraser could be playing popular Batman villain Firefly, a retired and disgruntled firefighter turned mad arsonist.

The casting notes for the role listed an actor in the 50-60s age range to play a “disgruntled former firefighter.”

While plot details have not been disclosed, the film will focus on Barbara Gordon, the daughter of Commissioner Gordon. Barbara Gordon is the most established version of the Batgirl character and was first introduced in 1961 imder the name Betty Kane. 

Batgirl currently has no set release date but will hit the streamer sometime in 2022. The current cast includes Leslie Grace as Barbara Gordon/Batgirl, Jacob Scipio in an as-yet unnamed role, and JK Simmons, who will be reprising the role of Commissioner Gordon aka Barbara Gordon’s father in the film.

Fraser, who headlined the action-adventure Mummy series, has had quite a career upswing this year. He landed the lead role in Darren Aronofsky’s next film The Whale, and after wrapping production on that, Martin Scorsese cast him for a key role in his next film Killers of the Flower Moon, starting Leonardo DiCaprio and Robert De Niro. He was also recently seen in Steven Soderbergh’s No Sudden Move. Fraser already had a home in the DC universe, playing Cliff Steele/Robotman on the HBO Max series Doom Patrol.

Batgirl will premiere next year on HBO Max, one of the first major DC properties produced exclusively for that platform. Christina Hodson penned the script and Kristin Burr is producing. Bad Boys for Life directors Adil El Arbi and Bilall Fallah are directing the film.
