I feel like I've seen a gazillion
Suicide Squad trailers recently, so many that I feel like I've already seen the entire freakin movie. Which is why it was so darn refreshing to get some inside secrets from the filming of the movie and what the cast were put through for their roles. Including having an on set therapist to prevent the actors from getting "too wrapped up" in their characters.
Apparently, Jared Leto was so heavily committed to his role as the Joker that he refused to see his co-stars off set. He wanted to make sure they saw him as nothing but the Joker. In preparation for his role, Leto sent his cast members live rates and ask them to fill their backpacks with 9 inch nails.
