Every good blockbuster mega-production needs a good hefty dose of comaraderie to get everyone through the long nights and arduous shoots.
Divergent, it seems, is no different.
We quizzed stars Shailene Woodley, Theo James, Kate Winslet and director Neil Burger on their funniest memory from the set.
One includes pants being pulled down. Enjoy.
Divergent is in UK cinemas 4 April 2014.
