Weve already heard rumours directors may cut Breaking Dawn in two, but Robert Pattinson, Kristen Stewart and Taylor Lautner have not yet signed up
In fact the rising Hollywood hotstars have only signed an agreement for four films, and would have to renegotiate their deals if an extra flick was added.
The small cast originally agreed on four movies, and have shot to worldwide fame after the Twilight Saga was an instant success on the big screen.
So if Summit does decide on splitting the final film in two it could be an incredibly costly exercise.
Meanwhile, fans are still eagerly awaiting the arrival of the third of the hit films, Eclipse.
