Florence Pugh says naked scenes were banned from \'The Little Drummer Girl\'.
The new BBC One spy thriller - which sees the 22-year-old actress star opposite Alexander Starsgard - won\'t be as racy as some of the channel\'s other dramas, including \'The Night Manager\' and \'The Bodyguard\', because of its US audience.
She told Radio Times magazine: "America is quite scared of bums and nipples. We had to make sure there were no bums and nipples out. I don\'t know why. Such strange people."
Florence admitted it caused some issues during filming, particularly during one scene in which the two stars were "under the duvet".
She explained: "There was one scene we did where Alex and I were under the duvet and supposedly naked. I was wriggling down one end and Alex is wriggling down the other.
"Halfway through, I hear: \'Cut! Cut!\' Director Park says, \'Florence, you\'ve got to hide your nipples more!\' I\'m like, \'OK!\'
"So we do it again, and again I hear: \'Cut! Cut! Florence - it looks like you\'re hiding your nipples.\' I\'m like, \'Arrrgh! Just let me get my breasts out, I don\'t care!\' But America does care."
The star was brought up watching "lots of European films", and she has never seen nudity as something to be ashamed of.
She added: "My parents were very cool and made sure we watched lots of European films when we grew up, so nudity has never been a problem for me, as long as it\'s done beautifully.
"There\'s a reason why there\'s a problem with bodies and it\'s because you never actually get to see any normal versions of them."
