Lionsgate has extended the contract of Jason Constantine as president of acquisitions and co-productions for its motion picture group.The studio said Constantine will continue to oversee the tracking and acquisition of all theatrical films. He will also oversee pre-buy projects in development, production and post-production and manage day-to-day operations of the acquisitions team. Constantine reports to motion picture group toppers Rob Friedman and Patrick Wachsberger, who assumed those slots a year ago when Lionsgate bought their Summit Entertainment. Constantine’s acquisitions include the “Expendables” franchise, “Cabin in the Woods,” “Arbitrage,” “Precious” and the “Saw” franchise. He acquired several titles in September at the Toronto Film Festival including Joss Whedon’s “Much Ado About Nothing,” “Girl Most Likely” and “Thanks for Sharing.” Constantine joined Lionsgate in 2000 from Trimark Pictures.
