The star of a brand new BBC drama previously acted in some film scenes.
French actress Clémence Poésy is the lead female in BBC drama Birdsong but she once appeared on screen in a film called Olgas Sommer.
The 29-year-old, who also played Eva Coupeau in Gossip Girl, starred in the 2002 film in which she played a 16-year-old girl who had fallen head over heels in love with a middle-aged man.
A movie insider told the Daily Star how much the blonde beauty impressed everybody on set and left a 'big impression' on the cast and crew.
They said: 'Her appeal hasn’t waned since her gorgeous curves made Olgas Summer a cult hit with her fans. It’s obvious why.
'Clémence might have only been 19 at the time but she made a big impression with this film – and not just with her acting.'
The French actress, who is most popular for her role in the Harry Potter movies where she played Fleur Delacour, will tease viewers with more bedroom antics in BBC's Birdsong.
The wartime set drama will see Clémence play the love interest alongside leading man Eddie Redmayne, 30.
She praised her gorgeous co-star and told Digital Spy: 'He's the loveliest, most generous, gentle... he's so genuinely interested in everyone, making everyone feel really special.
'Everyone just wants to talk to Eddie - when he shows up on set you kind of feel a general movement [towards him]! He's great, he's got everything, that guy.'
On her scenes with Eddie she said: 'Well, it's easier because it's Eddie Redmayne but it doesn't make it easy.
'What was great is that it was - this is going to sound stupid - it was a team effort. We were trying to get them right.'
