After a run like the cast of "Hunger Games" has had, you tend to get close -- like brothers and sisters.
In fact, Jennifer Lawrence said pranks are a constant on set.
"We all mess with each other to make sure all of us have a conflicted experience," Lawrence, 24, told Entertainment Tonight earlier this week at the 'Mockingjay – Part 1' premiere. "I got a Tiffany's box filled with crickets!"

"It was the most awful combination of feelings in the world," she added. "Tiffany's! Jeffrey! It was Jeffrey Wright [who plays Beetee]. I was like Oh my God, you didn't have to do that. Then I open it and it was a box of crickets. It was awful and they were in my trailer for months, I couldn't get them out."
In fact, she said she would try and take naps and would hear the crickets!
Her co-stars found it amusing.
"That was like the best prank ever pulled on anyone," Josh Hutcherson, who plays Lawrence's love interest in the film, said. "She's just fun to mess with."
"The Hunger Games: Mockingjay – Part 1" hits theaters on Friday.
