The training for a Marvel superhero role can require some ludicrous dietary restrictions — like Chris Hemsworth eating more than 6000 calories a day, mostly lean protein, to play Thor. Rudd didn’t have to get quite as yoked as Hemsworth, which means he probably didn’t have to eat quite as many broiled chicken breasts, but he still wasn’t allowed to eat or drink anything fun, as he explained:

“When I was having to train for the ‘Ant-Man movie,’ and I was on a very restrictive diet, my reward was sparkling water [laughs]. That’s how horrible that diet was. I was like, ‘Alright, I’m gonna have some sparkling water now, I’ve earned it.'”

Sparkling water is not exactly what I would call rewarding, especially because Rudd clarified that it wasn’t even flavored. It’s possible to imagine sparkling water as a treat if it has some kind of flavor, so he could at least pretend like he was ingesting something yummy (because even flavored sparkling water is just like the idea of a flavor, not an actual flavor), but plain, boring bubbly water as a treat is a pretty big stretch. What are we doing to these poor actors? I know their job is generally very fun and they get paid an exorbitant amount of money, but that level of dietary restraint for months on end sounds absolutely miserable.
