NEW YORK (AP) — The matriarch of the Cullen family in the "Twilight" films says talk of contract disputes are overblown.

Elizabeth Reaser, who plays Esme Cullen, says people need to understand contract negotiations are a part of showbiz.

It's been reported online that Ashley Greene and Kellan Lutz, who play vampires Alice and Emmett Cullen, originally had a three-picture deal and needed a new contract for the fourth installment of the franchise.

Summit Entertainment says it won't comment on negotiations or business discussions on its films.

The studio also won't say when filming is expected to begin for "Breaking Dawn," and Reaser hasn't been given a time line, either.

She says: "I really want to know because I'm trying to plan my life."

"The Twilight Saga: Eclipse" opens June 30.
