The film will begin shooting in autumn and will be produced by pop boss Simon Fuller.
He was the creator of Pop Idol and Spice Girl film "Spice World."
Simon's brother Kim who also wrote Spice World has written the new film.
It's about the adventures that a group of twenty-somethings get up to.
S Club dropped the 7 from the band name after Paul Cattermole left the group in March to join heavy metal act Skua.
