Brie Larson isnt above bathroom banter.

The Captain Marvel star revealed during a roundtable with The Hollywood Reporter published on Wednesday that she first talks toilets when meeting with new co-workers in the Marvel Universe.

Im the first person to email everybody because its very specific and very strange, Larson said of becoming a superhero mentor of sorts. People are like, I dont know how to do this. Yeah, no one does. Why would you?

The Room actor offered a sampling of what she tells the newbies.

Ill say, Train, because youll want to be as prepared in your body as you possibly can because it only gets harder as the job goes on. And really understand how to be able to go to the bathroom in your suit, she said.

The first Captain Marvel, it was a 45-minute thing to get me in and out of that costume, Larson explained.
