"Love scenes are strange anyway, but when you're doing a love scene with a person that you really have sex with? The only way to get through it was for us to all talk about the absurdity of it and make sure no one was feeling awkward."
Luckily, Pitt's instinctive protective skills came into play as soon as she called "cut".
"I couldn't get out of the bathtub to get to the monitor because the director is naked. We're artists and want to be free, but Brad - it's his wife. He was on towel duty. He'd hold the towel over me."
To add more pressure to the sex scene, Jolie admitted she felt insecure about baring nearly all after undergoing a preventative double mastectomy in 2013, but she hopes the scene will be inspirational to women who have gone through a similar medical drama.
"The surgeries still allow you to be a woman," she explained. "I hope other women - anyone who is worried about those issues and how your body can feel or look - can see that through the scene. I'm happy that will be in there if that answers something for them."
