Chris Pratt has revealed that he and Jennifer Lawrence needed a bit of Dutch courage before filming a sex scene together.

In an interview with The Telegraph, Pratt, who stars in the upcoming film Passengers with Jennifer Lawrence, said that both he and Lawrence had a drink before filming, in a response to rumours that she had to "get drunk" to go through with it.

"I don't know if it was like that [being drunk]," he said. "But look, actors aren't like pilots, operation equipment - and sometimes doing love scenes can be awkward.

"I've done a simulated sex scene before, so it was less weird for me, but for Jen it was the first time she'd ever done anything like that. So Morton said: 'Do you want to have a glass of wine?' Because just like in real life it takes the edge off a bit. And I imbibed as well. And, well, if that's what it takes to get comfortable, why not?"

Passengers is a sci-fi romantic drama starring Lawrence and Pratt as two space travellers who have joined a 120-year journey that will take them to a distant colony on another planet.

Everyone on board the ship is put into hypersleep, but Lawrence and Pratt's characters wake 90 years too early.
