Actress Sienna Miller was left shaking with tears running down her face after a marathon love scene session with her Live By Night co-star Ben Affleck.  Affleck plays notorious gangster Joe Coughlin in the crime drama, which he also wrote and produced. Sienna features in the film as Emma Gould. For the film, Miller and Affleck had to shoot several intimate scenes

Ben and I are like brother and sister, thank god, so there was no awkwardness. There was just a lot of stupid giggling. He’s very professional – I am not, but he is.

It is what it is
