• Though it's not always easy to take things from a movie set without getting caught, many famous actors have managed to take props home from sets to keep as mementos.
• Margot Robbie and her fellow "Birds of Prey" castmates said they have taken things like arm casts, bats, jewelry, and clothing from set.
• For example, Robert Downey Jr. said he took home a giant letter "A" from the "Avengers" set.
• Emma Watson said she took a few things from the set of "Harry Potter."
• Jennifer Lawrence said she took home Katniss' leather jacket and boots from the "Hunger Games" set.

Actors spend a lot of time on set, so it's not too surprising when they take home a few mementos to symbolize their time spent portraying a certain character.

Movie studios typically own the props that help make movies magical so it's not exactly easy for actors to swipe things from set. But sometimes stars find a way to take home some impressive or strange props.
