Producers of a new Carry On film insist the movie will still be made, despite losing cast members Danniella Westbrook and Shaun Williamson.

Carry On London was due in cinemas in December, with ex-EastEnders Westbrook and Williamson, but delayed when producer James Black was replaced.
"We are building up a new team and expect to start filming in 2005,"said Audra Woodburn of Carry On London Ltd.
It will be the first film in the comedy series since 1992's Carry On Columbus.
It will be the 32nd film in the Carry On series, which began in 1958 and starred Sid James, Kenneth Williams, Hattie Jacques and Barbara Windsor.
Carry On London was launched in July 2003 at a House of Commons event that saw then-Conservative leader Iain Duncan Smith pose for photos alongside actress Danniella Westbrook.
Westbrook was billed as "the new Barbara Windsor" while Shaun Williamson, who played Barry Evans in EastEnders, was due to play chauffeur Dickie Ticker in the new film.
Written by Brian Leveson and Paul Minett, who wrote ITV comedy drama The Booze Cruise, Carry On London tells of a limousine firm hired to take celebrities to the Herberts - the British equivalent of the Oscars.
"Shaun was keen and ready to take part but the project was delayed for so long that he is now busy with other work," said Williamson's agent Melanie Sacre.
"It was such a shame it didn't go ahead as planned because the script was absolutely marvellous - very funny and clever."

Danniella Westbrook is also no longer taking part in the film, her spokesperson confirmed, and ex-Spandau Ballet singer Tony Hadley no longer has a cameo role.
Producers originally said David Jason would feature in Carry On London, but his agent said he was never formally approached.
On Wednesday film-makers would confirm no cast members for the new film.
Carry On London will be directed by Terry Winsor, who worked on TV series Thief Takers and 1986 comedy Party Party.
Original producer James Black has been replaced by George Pavlou, who previously produced Little Monsters: The Birth, and Carry On founder Peter Rogers is executive producer.

No reason was given for Mr Black's replacement, and he was unavailable for comment.
"There has not been a Carry On film for 12 years, so we want to do it properly," said Carry On London Ltd's Audra Woodburn.
"We want to continue with the old historical aspects of the films while also encouraging a new generation to enjoy the Carry Ons."
