I understand that Sean Connery did wear a toupee in the Bond Movies.
One of my old friends is an actor and had a minor part in some film SC was in, a few years back. He told us that before Mr C came on set, the cast and crew were assembled and told there were two things no-one could mention in front of the diva. These were:
(a) hith lithp and
(b) hith thyrup.
