Benedict Cumberbatch pulled a no-no on the set of Avengers: Infinity War. Yes, the man behind Doctor Strange broke a cardinal Marvel rule, but he's living to not only laugh but also tell about it. Sort of. He won't give anyone the specifics, but he is one of the few to have read the entire script for the epic sequel. Even though he definitely wasn't supposed to.

Marvel is keeping all Infinity War secrets closely guarded. So much so that directors Joe and Anthony Russo kept the full script out of the actors' hands, only feeding them their pages one sheet at a time. This has helped ensure that no big spoilers get out. But somehow, Benedict Arnold, whoops, we mean Cumberbatch...Somehow managed to get his hands on the thick script, and he couldn't help but read it as fast as he could before it got yanked away. And now he knows ALL of the movies big secrets.

Benedict Cumberbatch will reprise his role as Doctor Stephen Strange in Infinity War. And we've seen him being tortured by the Black Order in the most recent trailer. He plays a key part in all the action, so he already was privy to quite a bit of the movie's true plot as it has been laid out. But he decided to take things a bit further than this Marvel co-stars, who played by the rules. Asked what he knows about the story, he couldn't hold back that he knows pretty much everything.

"Well, that's a loaded question, because I'm not supposed to have read the script. But I have. It's just mind-blowingly epic. What I thought is, this just doesn't stop. Once it starts, it does. Not. Stop. It's just this horrible, brilliant, terrifying, at times funny, at times very moving, relentless action. It's like everyone's constantly in crisis, and catching up with themselves, and it's really breathless to read a script like that. This isn't a slow burn. You're really thrown in helter-skelter. [Laughs] It's got a lot of facets to it, but I think the main one for me was just how utterly relentless the events and action were."

He doesn't give anything away really, but he sure does say a lot for someone who isn't supposed to have read the script, and broke a major Marvel rule. The good Doctor goes onto explain how he came to have the entire script in his possession. He explains that an exception was made that allowed him to be the ultimate Marvel rule breaker, even though we believe Mark Ruffalo still holds that unique description.

"Well, it's not Marvel's practice to hand around the whole script of any particular one of their enterprises, especially a film as big as this, and as secret as this. I kind of had to have a bit of an overview to understand what I was doing in it. Maybe I'm just a bit more stupid than the other actors involved. I just need a little bit of special care. And they were very sweet, and chained me to something immovable whilst I read it, and unchained me after I finished reading it."

Okay, so there was some cheating involved. Playing coy, the actor admits that he played dumb so that he could get his hands on every single word. But he's not Tom Holland, who is notorious for spouting spoilers at a moments notice.

"And this is where the interview gets dull! Because I can't really say. [Laughs] He's pretty actively involved, he's got quite an important Infinity Stone that's in his vicinity, and that draws him into the action, as well as a couple of other characters' plights, and stuff happens. [Laughs] That's about it! That's about all I think I can say," Cumberbatch said."

We don't have long to wait until we all know what happened in Infinity War. The movie is arriving early than expected, and will be in theaters April 27. Tickets went on sale this past week. We can think Entertainment Weekly for dropping this fun little nugget of info.
