Well, we had a fun few hours coming up with superhero possibilities for Martin Freeman’s character in upcoming Marvel sequel Captain America: Civil War – but it looks like you’ll be disappointed if you were hoping to see Freeman working his very own cape.

“I know who he’s playing in the film, but I guess it’s still a secret,” Civil War comic book writer (and Kick-Ass creator) Mark Millar told RadioTimes.com.

“The character is not a super-person, it’s somebody who’s… well, I don’t want to spoil it for anybody but he’s not going to be in costume.”

The writer (whose graphic novel The Secret Service was recently turned into the Colin Firth spy thriller Kingsman: The Secret Service) added: “He’s a great actor he could play anyone – he could play Hit-Girl!”

There go our hopes of seeing Freeman as the Green Goblin, Bullseye or Spider-Man, then – though Millar wouldn’t be drawn on any more details of his role.

“Once you get to see it, it’s so obvious,” Millar teased. “All I’ll say is, he’s not [Captain America villain] the Red Skull.”

Looks like it’s back to the speculation drawing board, then…

Kingsman: The Secret Service is out on Digital HD on May 24th and on Blu-ray and DVD on June 8th from Twentieth Century Fox Home Entertainment
