Amy Baer, senior VP of production for TriStar Pictures, has been upped to exec VP for the studio, ending an industry guessing game about whether she would go to Universal, sources confirmed Thursday.

Baer, 30, had been in talks to possibly move to U as an exec VP of production under the studio’s president of production Marc Platt, for whom she once worked at TriStar.

But she re-upped this week for a more lucrative deal with TriStar under studio president Robert Cooper.

Baer, exec VP of production Chris Lee and VP Rob Levine are the only senior execs in the TriStar ranks left from the Platt regime.

Baer is the primary exec on such big-ticket pics as the Julia Roberts starrer “My Best Friend’s Wedding”; “Zorro,” the Antonio Banderas pic that is headed into production soon; and “Donnie Brasco,” starring Al Pacino and Johnny Depp.

Cooper said Baer was a key executive in his strategy for the future of the studio.

“She’s an invaluable asset to this company,” Cooper said. “She is an executive of enormous intelligence, strength and integrity. Our upcoming slate is strong and diverse, for which Amy is largely responsible.”

Columbia TriStar Motion Picture Cos. vice chairman Lucy Fisher added: “Amy’s energy and enthusiasm are matched by her perseverance and good taste. People love to work with her.”

Baer has been with TriStar for four years. Before that she was with Guber Peters Entertainment Co. Her first job in the industry was with former CAA agent Jay Moloney as an assistant.
