Mughal-e-Azam

In 1962 British director David Lean offered him the role of Sherif Ali in his 1962 film Lawrence of Arabia, but Kumar declined the part. The role eventually went to Omar Sharif, the Egyptian actor. His next film Leader (1964) was below average at the box office.
Ram Aur Shyam
. In 1967 Dilip Kumar played a dual role of twins separated at birth in the hit film Ram Aur Shyam. His career slumped in the 1970's with films like Dastaan (1970) and Bairaag (1976), the latter in which he played triple roles failing at the box office. He took a five year hiatus from films from 1976 to 1981.
Saudagar
