Question for Aug 19-Gaurav Kane

I was born Krishna Pandit Bhanji in Snainton, near Scarborough,
Yorkshire, England, the son of Annalyna Mary (née Goodman), an actress and model,
and Rahimtulla Harji Bhanji, a medical doctor in 1943. In my teens, I changed
my name from Krishna Bhanji to X, fearing that a foreign
name would hamper my career.I have since been recognozed as one of
Britain's most acclaimed and well-known performers, I am one of few
men to have won all four major motion picture acting awards, receiving
an Oscar (for my most notable performance in 1982), BAFTA,
Golden Globe and Screen Actors Guild awards throughout my career. I
was knighted in 2001 and gained notoriety for insisting on being called
Sir X but after criticism by the bbc, I dropped my demand. Who am I?
