After years as studio insiders, Tom Sherak and Geoffrey Ammer are set to capitalize on their experience by offering consulting services to industry outsiders.

Former marketing execs Sherak and Ammer have formed Revolution Consulting Services and G2 Consulting Inc., respectively, as separate firms that share clients including Marvel Studios, Steve Bing’s Shangri-La, Level 1 Entertainment and Arnold Rifkin and Chris Eberts’ Rifkin-Eberts.

The two will assist the influx of players who are setting up shop in Hollywood and offering Wall Street dollars and other funds to studios for film productions.

The reason: Investing in a slate of films is relatively easy, but working with a studio can be daunting, even for those who are used to it.

“The people bringing money to the studios don’t necessarily know the dynamics of how the studios work,” Ammer said. “We know what happens because we know the inner workings of each department.”

Added Sherak: “We’re essentially sitting in rooms with people that we know. We understand the needs of the studios very well.”

Revolution and G2, set up at Marvel and Level 1’s digs in Hollywood and Century City, have lined up eight pics since forming two months ago, and have assisted producers with marketing and distribution concerns.

Those pics include “Iron Man,” “The Incredible Hulk,” “Rendition,” “Beowulf,” “Strange Wilderness,” “Shine a Light” and “Timber Falls,” as well as Revolution Studios’ last release, “The Waterhorse,” before the Joe Roth shingle shutters.

Last year, Sherak and Ammer had assisted MGM and Dean Devlin’s Electric Entertainment in marketing “Flyboys” before deciding to tackle other projects through their separate entities.

Sherak is winding down his partnership at Sony-based Revolution, which began in 2000. He was chairman of 20th Century Fox’s domestic film group before that.

The two had worked together at Revolution when Ammer handled marketing for the company’s films in 2000 before moving to Sony to become prexy of worldwide marketing for Sony’s Columbia TriStar Motion Picture Group, where he worked on the first two “Spider-Man” pics. He ankled the company in 2005.

Before Revolution, he had served as co-prexy of marketing in the Buena Vista Motion Pictures Group at Disney and spent 12 years in marketing at 20th Century Fox, where he worked with Sherak for eight years.
