Marvel's Paul Bettany is keeping mum on Vision's Captain America: Civil War future.

During Age of Ultron, the actor transitioned from the disembodied voice of Jarvis to the android casing of the Vision. Now, Stark's (Robert Downey, Jr.) former AI will have to choose a side as the Sokovia Accords tear a rift in the superhero world.

Unfortunately, Marvel's cone of silence left the actor little to talk about when Larry King broached the subject on Larry King Now.

"I can tell you very little because the moment I start to talk about it I start to see sunlight glinting off sniper rifles because they've got it locked down," Bettany joked. "They've got us locked down to secrecy."

Bettany did, however, dish on Vision's ability to wield Mjölnir. Until May's Avengers 2, only Thor (Chris Hemsworth) possessed the capability to control the Asgardian hammer. Now, however, Vision and his Mind Gem can also send villains flying with a single blow.

"It means that he's worth. Nobody so far in the Marvel Universe in these films has been able to pick up Thor's hammer, it's just too heavy for them," Bettany explained. "It's supposed to denote your worthiness and that you're a good man."
