"Saturday Night Live" Jinx?

I was hoping Eddie Murphy would win Best Supporting Actor at the Oscars last night, but alas, it was not to be. I'm wondering if the Academy has something against actors who appeared on NBC's "Saturday Night Live"

It started when Dan Ackroyd, who was a member of the very first cast of the show (1975-1980), was nominated for a Best Supporting Actor Oscar in 1989 for his work in Driving Miss Daisy. Ackroyd portrayed Daisy's son, a Southern businessman. Joan Cusack was nominated for a Best Supporting Actress Award twice -- once for Working Girl (1988) and In & Out (1997) -- for fine comedic performances. Bill Murray was nominated in 2003 for his great work in Lost In Translation. All of them, like Murphy, went home empty-handed.

So what's up? Because all of those actors are known for comedy, they're not to be taken seriously? Jamie Foxx played a lot of crazy characters on "In Living Color", but he won the Best Actor Oscar for the movie Ray, so that can't be it. They couldn't be ignored because they were on TV. Many Oscar winners appeared regularly on the small screen before they got on the big one. Look at Warren Beatty, who played a snotty teen on "The Loves of Dobie Gillis" or Tom Hanks, who was in drag most of the time on "Bosom Buddies", for example. I don't get it.
