Egyptian-born Omar rose to international stardom with his role in the 1962 epic Lawrence of Arabia — his first English-language film. He earned an Oscar nomination for his turn as Sherif Ali in David Lean’s iconic film opposite Peter O’Toole.

Omar followed the breakthrough performance with the title role in Lean’s Doctor Zhivago, co-starring Julie Christie. He then played Fanny Brice’s husband, Nicky Arnstein, in Funny Girl alongside Barbara Streisand.

His last completed feature film credits were in 2013.
