Gemma Arterton says she enjoyed working with Ben Affleck because of the improvisation that he would throw into the scene.
Arterton teams up with Affleck for new film Runner Runner; which sees the pair work together for the first time.
And the British actress revealed that Affleck would add some surprise things that weren’t in the script while they were working.
Speaking to OK! Magazine the actress said: "We had this weird back story and a relationship in the film years ago, and he has this possessive thing over me.
"My character is very dependent and cutting. In one scene Ben's character finds out that I've just had a night of intimacy with Justin's character and he gets very jealous and pounces on me - that wasn't in the script. It's fun but he really sprung it on me.
"There's a lot of that, he's a director as well so it was cool. I love all that stuff. I'm like, 'Bring it on, do something that's gonna freak me out!' What was on the page became much more than what was on the page, much richer!"
Runner Runner sees Justin Timberlake and Anthony Mackie join Arterton and Affleck on the cast list, while Brad Furman is in the director’s chair.
Arterton has also completed work on The Voices, and is currently filming Gemma Bovery; she is playing the title character.
Runner Runner is out now.
