In a major shakeup at Paramount Pictures on Friday afternoon, studio chairman Brad Grey fired Paramount Film Group president John Lesher and president of production Brad Weston.

Adam Goodman, previously president of production, will now be president of the film group, reporting to Grey. On business affairs he will continue to report to vice chairman Rob Moore.

Grey offered Lesher and Weston producing deals and said the new structure would “streamline its production executive stucture.”

Before moving to Paramount, Goodman had been DreamWorks head of production (DreamWorks split from Paramount in October). Goodman has worked on films including Tropic Thunder, Transformers, I Love You, Man and Disturbia.

“Adam has proven himself to be a terrific executive with a track record of having shepherded some incredibly successful films,” Grey said in a statement. “We have worked closely with Adam over the last few years and look forward to expanding his duties.”

Former Endeavor partner Lesher previously headed speciality division Paramount Vantage before being promoted to the main studio 18 months ago. He worked on films including The Curious Case Of Benjamin Button and Star Trek.

“John has made great contributions to Paramount and has nurtured a series of powerful films which have had a true cultural impact,” Grey said. “We look forward to working with him in the future.”

Weston came to Paramount in 2005 and previously served as co-president of Dimension Films. He took the head of production post in January 2007.

Grey added: “Brad’s strong relationships with filmmakers, his creative instincts and hard work have been strong assets for our studio. We look forward to entering into the next phase of our relationship with him.”
