Speaking about their chemistry, Scots star Butler said: 'We have a blast together and she appreciates that Celtic manner.
'There's nothing diva-ish about her, she's very down to earth, very sure of herself and who she is, and I'm like a little kid, who doesn't take myself too seriously.
'We had a fun script and a great director, so we just had to dive in and it was a blast.'

Are they or aren't they: Jennifer posed proudly with the Scots actor at the Vue cinema in Leicester Square,
'I think that it’s sort of just a formula – that they think that if you do a movie together and you get along really well – you must be dating…. It’s fodder – it fills magazines, it has nothing backing it at all,' she said.

He told Men's Health magazine: 'I get laid less now than I used to, because I’m way more paranoid now. Look at f***ing Tiger Woods.'I mean, I’m nowhere near as naughty as I used to be, partly because I did a lot of that when I was drinking.
'I’m not saying I’ve cut that part out. I’m certainly no angel. There’s no smoke without fire.'
Since moving to Hollywood five years ago, Butler has only had two relationships.
He explained: 'I’m not a big relationship guy. One of my vices is, I’m too wrapped up in myself and not always in a good way.'
