William Morris Independent’s heads Cassian Elwes and Rena Ronson will leave the merged William Morris Endeavor (WME) Entertainment superagency, a company spokesman has confirmed.

Endeavor Independent head Graham Taylor will now run the independent film arm of William Morris Endeavor.

The spokesman didn’t reveal how the rest of the department will be staffed. Jerome Duboz is understood to be staying on.

WMI co-heads Elwes and Ronson worked on films such as Monster’s Ball, The English Patient, Pulp Fiction, and Half Nelson in their years at WMA.

The pair were in Cannes representing projects such as Blue Valentine, starring Ryan Gosling and Michelle Williams (co-represented with Endeavor). That film was one of the title’s backed by WMI’s Incentive Filmed Entertainment $100m production fund.

Taylor’s team at Endeavor includes Liesl Copland, Alexis Garcia and Mark Ankner, all of whom are expected to stay on in the as-yet-unnamed indepedent arm of WME.

The merger, speculated for months, was announced on April 28. The merger is expected to be completed in the second quarter of 2009.
