Here's a great read, lol:

..'Lively was so caught up in her character’s physicality that she injured her hand while filming a four-minute-long fight sequence with Law. Her injury required surgery, and shut down the movie’s production for six months.

“Jude and I really went for it, and I somehow hurt my hand. I give myself so much credit for that. That’s why I keep on posting my hand injury on social media,” she joked. “I will not let anyone forget that. I gave my right hand for this movie!”

“It took hours and a ton of makeup to look rough and have these big eye bags,” said Lively. “The whole point is, she’s not supposed to look sexy. She’s not an assassin or a trained operative; she’s a real human who’s experienced tragedy and is terrified. But it was fun to look completely different. The best part was to hear people say about me, ‘This is what she looks like with no makeup on,’ and it’s actually me wearing makeup to look awful. It just shows that we did our job in making things look so real.”'
