Sir Lawrence Olivier was one of the very first major stars to appear in a commercial, well before Orson starting his career as a shill. Polaroid paid Olivier $300,000 to do one spot. Everyone liked it and Larry cashed the check, apparently without a bit of humiliation.
I was once told from someone who'd been on the set that Orson referenced Mason wines off camera as "horse **** ," but he took their money, shilled for them by renting whatever public prestige and believability he still had with the public, and cashed the check.
The films of his magic that I've seen weren't even remotely good performances except for the beginning one which had John and Cathy Daniel as assistants and the last performance which came off because he'd been taught the Hindu Yarn by Mike Caveney. All the other material in between was pretentious and, in most cases, unintelligible.
