You probably know that Jennifer Lawrence inherited the role of Mystique in the X-Men movies from Rebecca Romijn. But did you know that the elaborate makeup process required to turn Lawrence into a scaly blue mutant used to take eight hours? After a few movies, the X-Men makeup department was able to get that number down to about three hours by incorporating makeup and a body suit; previously Lawrence’s entire body was painted from head to toe. That’s just one of the uncanny facts featured in the latest episode of You Think You Know Movies!

Lawrence didn’t have to put on nearly as much makeup to play the role of Katniss Everdeen in The Hunger Games, but sometimes she would show up to set still wearing some of the fake dirt and grime from the night before, earning her the on-set nickname “Catpiss Neverclean” from co-star Elizabeth Banks. To pull off Katniss’ impressive feats with a bow and arrow, Lawrence trained with an Olympic archer, and even injured herself several times.
