While All Saints leader Shaznay Lewis hones songs for the band's sophomore album, the remaining members of the British quartet will spend their time working on a new film, entitled "Honest," to be directed by former Eurythmic Dave Stewart.

The trio of Saints -- Melanie Blatt and sisters Nicole and Natalie Appleton -- will make their feature film debut in "Honest," a movie which tells the story of three sisters who rob banks in London's West End during the 1960s while dressing as men, according to a report in "Variety."

The All Saints aren't expected to contribute any new material to the film or its soundtrack, but members of the group may end-up lending their individual voices to separate songs.

The screenplay for "Honest" was penned by the duo of Dick Clement and Ian LaFrenais, the team responsible for "The Commitments," "Still Crazy" and the upcoming sequel to "Bad Boys." "Honest" is still considered to be in the pre-production stage, and actual on-location shooting isn't

expected to get underway for several months.
