Marvel Studios doesn’t really employ snipers, but the studio is serious about keeping secrets. One of those secrets is Jude Law’s role in Captain Marvel. He may be Mar-Vell, as many fans assume, or he could be someone else entirely.

“I can’t tell you who I am,” Law said on The Late Show with Stephen Colbert. Law wouldn’t even give the slightest hint, as he shared a hilarious story about just how intense Marvel security was on set. If Law had any hopes of being the next Tom Holland or Mark Ruffalo, they were quickly dashed.

Captain Marvel is in theaters March 8, 2019.
