Richard Briers and Sir Cliff Richard are among 80 uncredited actors and celebrities who will waive their fee in an adaptation of Ray Cooney's 1983 play Run For Your Wife. The money will instead be donated to a theatre charity.
Danny Dyer will star in the film about a man who has been happily involved in a bigamous marriage for several years.
Girls Aloud's Sarah Harding, Men Behaving Badly's Neil Morrissey and Denise Van Outen will star in the film, to be released some time next year.
A spokesperson revealed that the stars waived their fees because they knew Ray Cooney, who is directing the adaptation, really well.
Cooney has explained that film companies had offered him large amounts of money to produce the movie, but has instead opted to film it in the UK under a modest budget.
"I have come up with what my colleagues all think is a terrific screenplay," he wrote on his website.
"None of the humour has been lost from the original stage version, but it has been 'opened up' in a way that anyone who missed seeing the stage version (is there anyone?!) would never guess its 'theatre' background."
Rolf Harris, Maureen Lipman, Prunella Scales, Dennis Waterman, Sylvia Sims and June Whitfield will also film short cameo roles.
Bernard Cribbins appeared in the original West End production, which ran for eight years.
Danny Dyer recently declared that a quarter of the films he stars in are "s**t".
