Warner Bros. production topper Jeff Robinov has promoted longtime lieutenant Kevin McCormick to Robinov’s old job.

McCormick, formerly exec VP of production for the studio, is now prexy of the division. Move follows Robinov’s elevation to prexy of the newly created Warner Bros. Pictures Group as part of Time Warner’s ongoing streamlining efforts.

McCormick assumes day-to-day responsibility for development of studio pics, working closely with Robinov on the slate they present to studio prexy-chief operating officer Alan Horn for greenlight approval. McCormick will continue to oversee the division’s Gotham and London offices.

Robinov said there was never any doubt that he would move McCormick up, noting they’ve worked well together for nearly nine years. He praised the exec’s integrity, taste and relationships with filmmakers.

“He brings a world of experience to the job,” Robinov said.

Under the restructuring, Robinov will work more closely on the marketing and distribution of pics such as “Speed Racer,” “Get Smart” and “The Dark Knight,” while McCormick focuses on creative affairs.

Robinov said the duo will continue their efforts to develop tentpole movies for the international and domestic markets in their expanded roles.

“It’s really an extension of the relationship Jeff and I have been working under for the last year,” McCormick said, noting that the two will set the agenda together “and I will increasingly be the one to implement it.”

McCormick joined the studio as exec VP of production in 1999. He supervised projects including “Blood Diamond”; “Sweeney Todd,” a co-production with DreamWorks; and David Fincher’s upcoming “The Curious Case of Benjamin Button,” a co-production with Paramount.

Other projects he has overseen are “The Last Samurai,” “The Perfect Storm,” “Syriana” and “Tim Burton’s The Corpse Bride.”

Previously, he served as exec VP of production for Fox 2000 from 1995-99.

He began his career at the Robert Stigwood Organization in London.
