The final installment in the TWILIGHT movie series is facing delays as film bosses attempt to renegotiate pay deals to keep all of the actors on board for a fifth picture.
The last movie, The Twilight Saga: Breaking Dawn, is based on Stephenie Meyer's fourth book and film chiefs are planning to expand the franchise by splitting the picture into two.
But bosses at Summit Entertainment have been slowed down by negotiations with some of the supporting cast who are reportedly demanding a pay increase to return for a fifth movie.
And film chiefs are allegedly planning to recast some of the parts if appropriate salary deals can't be reached, according to the Hollywood Reporter.
A source tells the publication, "We may have a situation where one of them is thrown out on the street to make a point. This thing is gonna be two movies, with or without the cast intact."
Summit chiefs are also reportedly considering moving production to Louisiana in a bid to cut costs - the first installment was filmed in Portland, Oregon, while the second two boasted location shoots in Italy and Vancouver, Canada.
Shooting on the two Breaking Dawn films is slated to begin in the autumn (10), with both movies being shot back-to-back ahead of possible releases in November 2011 and summer 2012.
