In a change of pace following the historic epic "The Last Samurai," Ed Zwick and his Bedford Falls shingle are looking to Columbia Pictures to strike a lighter note. Zwick is in negotiations with the Culver City studio to direct, produce and co-write the romantic comedy "Happy Endings." Details on the story line are being kept under wraps. Zwick's Bedford Falls partner Marshall Herskovitz will co-write and produce the project with Zwick. Matt Tolmach and Amy Baer will oversee for the studio. Zwick's directing credits include "The Siege," "Leaving Normal," "Glory" and "About Last Night." He and Herskovitz also have a long list of producing credits, including "Traffic" and "I Am Sam." Zwick and Herskovitz also recently received a series commitment from ABC and Touchstone TV for an ensemble drama, "1/4 Life." They are repped by CAA.
