Being a gentleman of a certain age, I was crying paroyxsmically throughout Tom's Willy Tanner impressions.
Max Wright, like Robert Reed before him, always thought that he was too good to play a sitcom father and that his career had been less than it should have been because of it. Very few actors wouldn't trade their own careers for even one multi-year run on a dumb sitcom. Although I have heard terrible things about the behavior of ALF's puppeteer.
A fellow FOT reminded me that both the creator of ALF (Permanent Midnight) and Max Wright later fell under the spell of one of the White Ladies. It was apparently rough going.
