"(Costner) was constantly in Ted's face about what he was doing wrong, criticizing him repeatedly about his setups in front of Paula Weinstein (one of the film's producers). He said several times loudly to anyone who would listen, 'This movie will take a year to shoot if you don't get rid of Ted,'" an unidentified source said, World Entertainment News Network reported Thursday.
The situation reportedly climaxed when Griffin asked Costner to return to his trailer and Costner yelled back, "I will not. Not until you change the lighting set up like I told you."
Costner has directed several films and won an Oscar in 1990 for best director for "Dances with Wolves."
Costner is said to have told MacLaine "You keep out of this."
Jennifer Aniston also stars in the as-yet-untitled, and now directorless, film.
