I think Sir Alec resented that a lot people from the 1980's onwards only really associated him with the Star Wars films - and was the major topic of converstion whenever a fan met and talked to him.

This is a man who has a lifetime of distinguised acting work - from the Ealing comedies (which I urge anyone to watch for his comedial timing and delivery), to Kafka, A Passage To India, Laurence Of Arabia, Cromwell, Bridge On The River Kwai and Tinker, Talior, Soldier Spy to name but a few.
