UPDATED: Rob Moore is leaving his post as the vice chairman of Paramount Pictures, Variety has learned.

Moore, who didn’t respond to requests for comment, has been in his current job since 2008 (and with the studio since 2005), overseeing Paramount’s worldwide marketing, distribution, digital and television arms, and shepherded tentpoles like the “Transformers” and “Mission: Impossible” franchises, “Interstellar” and “The Wolf of Wall Street.” The studio does not expect to fill Moore’s position.

A source close to the situation said that the decision to ask for Moore’s resignation was made by the board of Viacom, Paramount’s corporate parent. Moore had been one of the major proponents of former Viacom Chairman Philippe Dauman’s push for Paramount to sell a minority stake in the company to Dalian Wanda. But after Viacom Board Vice-Chair Shari Redstone successfully orchestrated Dauman’s ouster last summer, the decision was made to abandon the sale process over Moore’s objections.

The source also said that Moore’s management team including worldwide distribution and marketing president Megan Colligan and motion picture group president Marc Evans are expected to remain at the studio, with some of the team taking on expanded roles.

Moore’s exit comes as the studio is having a particularly turbulent year at the box office, with costly flops such as “Ben-Hur,” “Teenage Mutant Ninja Turtles: Out of the Shadows” and “Zoolander 2″ piling up. This week, Viacom said in public filings that Paramount would take a $115 million write-off on the still unreleased “Monster Trucks,” which bows in 2017. Following the exit of Dauman, Viacom’s leadership gave a vote of confidence to current Paramount chairman Brad Grey, however, many in Hollywood believe his days are numbered given the studio’s poor performance, which is expected to lose close to $500 million on its current slate.

Industry insiders consider Jim Gianopulos, the former chairman of Twentieth Century Fox, a viable candidate to succeed either Grey or Viacom’s interim CEO Tom Dooley, who stepped down this week.

Gianopulos said, however, that he has had no discussions about either position.

A spokesperson for Paramount declined to comment.
