"It was not until July 20th that Summit was first informed of Ms. Lefevre's commitment to Barney's Version, a commitment we have since been advised she accepted in early June. Summit had acted in good faith that she would be available to fulfill her obligations both in terms of rehearsals and shooting availability for The Twilight Saga: Eclipse. We feel that her choice to withhold her scheduling conflict information from us can be viewed as a lack of cooperative spirit which affected the entire production.
Furthermore, Ms. Lefevre took a role in the other film that places her in Europe during the required rehearsal time, and at least 10 days of [Eclipse]'s principal photography. This period is essential for both rehearsal time with the cast and for filming at key locations that are only available during the initial part of production.
Contrary to Ms. Lefevre's statement, it is simply untrue that the studio dismissed her over a 10-day overlap," the statement concludes. "It is not about a 10-day overlap, but instead about the fact that The Twilight Saga: Eclipse is an ensemble production that has to accommodate the schedules of numerous actors while respecting the established creative vision of the filmmaker and most importantly the story."
