London, April 12 : Bjorn Ulvaeus, who co-wrote the Abba songs on which Mamma Mia! is based, has become embroiled in an extremely awkward dispute with his fellow producers over whether such a sequel of the musical should be made.

At a party at the Café de Paris to celebrate the 10th anniversary of the hit West End show that inspired the film, the Swedish musician said he's against a sequel to the film.

"It wouldn''t work. I don''t think we would do a sequel. We have moved on to other projects now," the Telegraph quoted Ulvaeus as saying.

Ulvaeus feels that a follow-up `would be made for all the wrong reasons'.

A pal of the 63-year-old songwriter has claimed that Ulvaeus believes such a film would be produced only to add to the 434 million pounds that the original has made around the world and would have no artistic justification.

"He says that all the most popular songs have been used in Mamma Mia! and he is more interested in his other projects," said his pal.

However, executives at Universal, the Hollywood studio, are believed to be `desperate' for a sequel.

Judy Craymer, one of the film''s six producers, says she is determined to persuade Ulvaeus and his fellow Abba songwriter, Benny Andersson, who composed additional music for the film, to give the go-ahead. (ANI)
