Colton Gramm is leaving his post as WMA agent to become the first talent representative brought into the fold of Original, the management and production company that Marty Adelstein and Neal Moritz hatched last month.

Gramm moves into management after stints at ICM and most recently WMA, where he assembled a list of up-and-coming actors. He will continue to represent Timothy Olyphant, who starred in “Go” and recently completed the Lawrence Kasdan-directed adaptation of Stephen King’s “Dreamcatcher” for Castle Rock, and Gary Dourdan of the TV series “CSI.”

Gramm began as a trainee in the ICM mailroom working on the desks of Jim Wiatt and Toni Howard, and also worked with WMA clients John Leguizamo, Scott Wolf, Michael Sheen (“The Four Feathers”), David Koechner (“Wakin’ Up in Reno”), Brian Van Holt (“Windtalkers”) and Jeremy Piven. It is unclear whether they will join the Original ranks.

Endeavor founding partner Adelstein and Original Films’ owner Moritz merged their assets to form the new company last month.

Moritz brought his considerable producing business, which has films either in production or in development at every major studio and includes “The Fast and the Furious 2” and Revolution’s summer action drama “XXX.”

Adelstein brought his client list, which includes David E. Kelley, Bonnie & Terry Turner, Simon West, Jan De Bont and the Rock.
