Being at 39, I've discovered Carry Grant's talent just a month ago. Since then watching his talent on screen brought a spark of brightness to days that happened to be quite rough.
Had this been asked few months ago I'd probably gave the same answer.
That's said, have some kindness for us. Masterpieces are getting undeservedly buried under pile of garbage produced by major companies nowadays, so discovering amazing talents is like a breath of fresh air.
That said, check out Charade. It's amazing.
EDIT: crap, no, 45 is right.
