EXCLUSIVE: WME has just signed Peter Segal and his Callahan Filmworks producing partner Michael Ewing. The duo has been on the move lately. They left CAA in April to rejoin their longtime agent Adam Kanter at upstart agency Resolution. Now they have moved again. Segal most recently helmed the Warner Bros comedy Grudge Match, which stars Robert De Niro and Sylvester Stallone as former boxers who get in the ring one last time to settle a long dispute. Callahan Filmworks produced with Bill Gerber. Segal’s comedy credits include Tommy Boy, The Longest Yard, 50 First Dates, Anger Management and Get Smart, so it’s a good get for WME. Segal is still repped by attorney Lawrence Rose.
