Actors who rejected films and later on felt guilty

Aamir Khan: "KKK...Kiran" from 'Darr' was earlier to be said by Mr Perfectionist Aamir Khan, but Mr. Perfectionist did not want to portray himself as a negative character in the early phase of his career, so, King Khan bagged up for this role and later on he received National award. After 'Darr', Shah Rukh Khan acted in many Yash Raj movies like 'Dilwale Dulhaniya Le Jayenge', 'Dil Toh Pagal Hai' and many more.
