Rob Guralnick was hired Tuesday by Mosaic Media Group — another signal of talent management companies’ effort to push more aggressively into film production.

Exec, who spent 14 years at Warner Bros., most recently as exec VP, will attempt to mobilize three to five movies per year and help start an urban film division. Mosaic’s components include Atlas Entertainment, Gold/Miller and Family Tree Mosaic, a strategic alliance with urban music management concern Family Tree Entertainment.

“Atlas will (focus on) mainstream fare, Gold/Miller will make the comedies, and Family Tree’s Michael ‘Blue’ Williams will help us move into the urban film business,” said Chuck Roven, Atlas Entertainment president and Mosaic partner. “We needed someone to put the pieces together and reached out to Rob because … he’s been through the wars and knows how to deal with big stars and young talent.”

Roven and his team co-produced “Scooby-Doo,” which Warner Bros. releases June 14, and “Bullet Proof Monk,” which Mosaic is making through MGM/Signpost, with Chow-Yun Fat in the starring role. Roven expects to start production this year on “Border Town,” a drama scripted and to be directed by Gold/Miller client Gregory Nava at MGM, and hopes to follow with “The Brothers Grimm.”

Despite Mike Ovitz’s high-profile problems with AMG, integrated management companies like the Firm, Brillstein-Grey and 3 Arts have attracted attention lately for their drive to package, produce and finance films and TV shows driven by clients. Mosaic’s client lists include Alanis Morissette, the Goo Goo Dolls, Outkast, Green Day, Wallflowers and Jagged Edge. Film clients repped by Gold/Miller include Jim Carrey, Ellen DeGeneres, Garry Shandling, Will Ferrell, Kevin Sorbo, Marlon and Damon Wayans, and directors Jay Roach and Judd Apatow.

Mosaic has a first-look deal at MGM and another pact with Signpost, in which Mosaic is a founding partner. None of this guarantees financing, but the potential lured Guralnick. After his long run at Warners presiding over films ranging from “The Bodyguard” to “You’ve Got Mail,” he left the studio in early 2001.

“These companies … might well be the future of what entertainment conglomerates can be, and they are leaner and less set in their ways than studios,” Guralnick said. “The deals with MGM and Signpost allow me to continue to be a buyer, and there are 50 or so projects in development here.”

Said Gold/Miller partner Jimmy Miller: “We are managers first and foremost, but the Signpost and MGM deals have created opportunities for clients. When Chuck said he wanted to hire Rob, we knew he was an executive we could put our guys in a room with.”
