The Glorious 39 director Stephen Poliakoff and the film's star Romola Garai headed to an intimate private drinks reception at Kettner's in Soho, to celebrate the film's British premiere at the London Film Festival.
Garai, 27, who recently starred in a BBC1 adaptation of Jane Austen's Emma (adapted by Poliakoff's screenwriter wife Sandy Welch, who was also at the soiree) had taken off her platform sandals by the end of the night, because they were sky high.
Dressed in Burberry and bright red lipstick, Garai had invited a group of her pals to join the Glorious 39 cast at the party.
Jenny Agutter and Hugh Bonneville mingled with Bill Nighy, who, with Garai, reprises the father-daughter relationship first seen in the 2003 movie I Capture the Castle.
Poliakoff's new British thriller is set against a backdrop of pre-World War Two Britain and the party's music included the film's soundtrack by Poliakoff's long-time collaborator Adrian Johnston, as well as some wartime classics.
The film marks Poliakoff's return to the cinema after an 11-year absence his previous feature films include the 1991 hit Close My Eyes.
Arriving at the premiere early, David Tennant, who plays a family friend in the film, appeared in an expansive mood. And Poliakoff was also in celebratory mode, saying of his new leading lady, Garai: "I'd been following her with great interest. I needed an extraordinary talent and she is an extraordinary talent that holds this film together. I think she is our next big star, our next Kate Winslet."
