Singer Emma Bunton says the Spice Girls are planning to come together to make a sequel to their 1997 film “Spice World.” Spice Girls Victoria Beckham, Bunton, Geri Halliwell, Melanie Brown and Melanie Chisholm announced earlier that they were developing a West End stage musical based on their hit songs with Judy Craymer, who produced “Mamma Mia!”, reports a website. Bunton added the girls hoped to turn the stage musical “Viva Forever” into a major movie to rival “Mamma Mia!” “We're involved in the new Spice Girls film, which is being done by Judy Craymer and the team behind “Mamma Mia!” We mail each other the ideas and are overjoyed that it's happening,” she said, adding, “We would've liked to do another film but after “Spice World”, there was an album, then a tour and then Geri left, so it didn't happen.”
