Thierry Wase-Bailey is standing down as managing director of UK-based sales operation HanWay.
Wase-Bailey is being replaced by Tim Haslam, who was president of international distribution at Intermedia before Jere Hausfater took over.
Wase-Bailey, who has headed HanWay for four years, is to focus on developing his own sales and consultancy business, EntCo.
"Thierry is a formidable salesman," said Jeremy Thomas, producer and chairman of HanWay's parent company, Recorded Picture Company. "He leaves with all our best wishes and I hope to continue our collaboration with Thierry and EntCo into the future.
"I worked with Tim back in his Majestic days. He's a consummate professional and shares our vision of where the independent business is going."
At Intermedia, Haslam was responsible for the sale and distribution of films such as Spike Jonze's Adaptation and Phillip Noyce's The Quiet American. He was also director of sales and distribution at Majestic Films & Television, where he was responsible for the international distribution of Dances With Wolves, The Piano, and Driving Miss Daisy.
"I have always dreamt of collaborating with a hands-on producer such as Jeremy, who consistently produces distinctive movies and is creatively truly independent and innovative," said Haslam.
HanWay's slate currently includes $25m CGI animated picture Back To Gaya, which is now in post-production, Bernardo Bertolucci's The Dreamers, and Young Adam, starring Ewan McGregor. Shooting next year is Don't Come Knocking, directed by Wim Wenders and starring Sam Shepard, Jean Reno and Jessica Lange.
