In the animated film "Free Birds," two turkeys from opposite sides of the tracks must put aside their differences and team up to travel back in time to change the course of history - and get turkey off the Thanksgiving menu for good.

The film's co-stars Owen Wilson and Woody Harrelson had to be split apart while they worked on the project because they spent too much time goffing off.

Prior to the film's theatrical release, Wilson confessed that he and Harrelson joked around too much, prompting director Jimmy Hayward to split them up.

He told the New York Daily News, "We made the argument we can bounce (ideas) off each other. There were two sessions and Jimmy Hayward didn't feel they were productive. Jimmy ended up separating us, and that was more efficient."

Harrelson added, "We thought we were good. But Jimmy separated us as we were not getting enough done."
