Twilight stars dispute over pay

The cast of the final installment of the Twilight series could be altered due to a dispute over pay.

Stephenie Meyer's fourth and final Twilight novel, Breaking Dawn is thought to be split in to two films due to its size and content.

Summit Entertainment have been in talks to renegotiate the actors' contracts as a result of the change but it's thought that two actors in particular are not happy with the salary offer.

Main stars Robert Pattinson, Kristen Stewart and Taylor Lautner are reportedly close to signing but Kellen Lutz and Ashley Greene have yet to commit to the film.

Kellan and Ashley play Emmit and Alice Cullen respectively, the siblings of main character, vampire Edward Cullen, played by Robert Pattinson.

It's reported that the actors want a higher salary as they are now sought-after stars and the films are likely to be made back-to-back, meaning they'd be unable to accept other offers.
