Marketing maven John Durie has quit Manifesto Film Sales to set up his own marketing boutique.Durie’s departure follows organizational realignments at Manifesto that have seen his role — originally that of co-managing director with sales chief Aline Perry — downgraded. Durie was one of the founders of Manifesto in 1989. He has created marketing campaigns for 30 titles and positioning Manifesto’s corporate profile within the industry. In the last year he has also been responsible for the U.K. distribution of all Manifesto titles. These have included “Barton Fink,”"Bob Roberts,”"The Crying Game” and “Reservoir Dogs.” Per Durie, he will provide marketing services to a small number of clients, including sales agents and foreign theatrical distribs. Durie’s U.K. responsibilities at Polygram will be undertaken by Chris Bailey. The company is looking to recruit a replacement to take on foreign marketing chores.
