1. The majority of the cast got "SKWAD" tatooed on them.
Some of the tattoos were done by Margot Robbie!
2. Ryan Gosling was first asked to play The Joker but turned it down because he didn't want to sign a multi-movie deal.
3. The baseball bat Harley Quinn used was given to filmmaker Kevin Smith, who is a huge fan of the character!
He even named his daughter Harley!
