They say not to mix business with pleasure.

But it seems nobody told that to  and Elsa Pataky.

The actor has revealed exactly what it was like filming love scenes with his 41-year-old wife Elsa when the couple played husband and wife on the film 12 Strong.

Appearing on breakfast TV show Sunrise, the 34-year-old said his wife would ‘boss him around’ on set.

‘We had about seven or eight year’s rehearsal time to play these characters,’ he said.

‘If we didn’t have any chemistry we’d be in trouble.’

The Thor star added that starring in the movie together acted as a mini-holiday ‘away from the kids’.

The couple share three children together: India Rose and twins Tristan and Sasha.

When it came to filming the film’s love scenes, Chris told Sunrise hosts Samantha Armytage and David ‘Kochie’ Koch that it wasn’t exactly the kind of environment they were used to.

‘How do you do a love scene with your own wife with a crew standing around?’ Sam asked the star.

‘Yeah, that’d be the big difference,’ Chris replied adding ‘the cameras and the lights… that we weren’t accustomed to.

Sam cheekily added: ‘Well we should hope so’.

‘It’s not a usual setting for us definitely,’ Chris said.

As for whether or not he would work with his wife again, Chris kept his answer rather cryptic telling the hosts: ‘Of course I would. How am I supposed to answer that?’

12 Strong tells the story of the first Special Forces team that’s deployed to Afghanistan following the events of 9/11.

In the film, Chris plays the role of Captain Mitch Nelson, who has the task of leading his team of 12 soldiers to take down the Taliban.
