Lucy Punch has started shooting The Wedding Video around London.
The Bad Teacher star appears in the romantic comedy, which sees a reunion between Calendar Girls' director Nigel Cole and writer Tim Firth.
Comedian Rufus Hound and Peep Show's Robert Webb also star in the film, which has been described as an expose on English society weddings in Spinal Tap-style.
The film details the story of a shambolic yet loveable best man who decides the greatest gift he can give his friend and his bride is a video of their wedding - but things don't quite end up that way.
It is the first collaboration between Nigel and Tim since the 2003 comedy Calendar Girls, which starred Helen Mirren and Julie Walters.
The Wedding Video is scheduled for a 2012 release.
