His name was YUL Brynner. You'll have better luck finding out about him if you spell his name right. I agree that is not an easy thing to do...
Here's a link to a site
with video clips of his roles, by the most famous of which was the King in "The King and I." He owned that role!
He died in 1985..... not hard to see why it might be difficult to find info on him!
