It seems production was moving slowly on the moment in the new thriller, due in part to the shyness of her co-star Idris Elba and director Hany Abu-Assad.
Winslet recalled on The Graham Norton Show: “I had to get quite bossy.
“I’ve done quite a lot of these scenes before and poor Hany was really quite nervous and had an extensive shot list and I thought, ‘We are never going to get this done.’
“Idris was a bit nervous too and everything was moving a bit slowly so I just said, ‘Okay boys, this is what we are going to do…’’
She added: “We just got on with it.
“We got naked but Idris asked me to keep my socks on – I thought he didn’t like feet but, it is the opposite, ladies and gentlemen; Idris loves feet!”
As part of promotion for the new movie, Winslet has also been speaking of another one of her famous co-stars: Leonardo DiCaprio, with whom she worked in Titanic.
“I think for Leo and I it was seven months of very intense work, we were both really very young,” she told ITV’s Lorraine.
“And luckily, and this was the fortunate thing, we never fancied each other! I know that’s really annoying to hear, sorry. We really never did.”
“So it did mean that we were able to have this… be able to tease each other, which we still do, which is really amazing.”
