I'm thinking it's Kiefer Sutherland. First he has been in movies with all three and it ain't - Robert Downey Jr - some movie called 1969, although I think Kiefer was also good pals with Robert Downey back in the day going so far as to live with Robert and Sarah Jessica for a time. He appeared with Christian Slater in Young Guns and Jack Nicholson in a Few Good Men. Besides Ted refers to this blind as Wrangler Dangler and Kiefer was in some cowboy movie called "Rider up" and Kiefer stopped acting for a couple of year's while he went on the rodeo circuit as calf roper. And we all know how cute cowboy's bums look in Wranglers
Kiefer has a well documented history of alcohol abuse recently resulting in a stay at the gray bar hotel. Ted also mentions a "series" which to me refers to TV - 24, and "base" boy which could be guitars, which Kiefer has a large collection of. Maybe Ted mentions the oscar to throw us off because Kiefer won a Golden Globe for 24. Just my thoughts........
