The guy had an uncanny knack at being a real jerk on film. He also seemed to have a good sense of humor about being typecast as the jerk authority figure, with appearances in Van Wilder and Not Another Teen Movie.
I just watched him in Trading Places, and he's always on TV in The Breakfast Club and Die Hard, but looking at his stuff on imdb, he's been in a ton of stuff (both TV and movies) that I don't even remember him in.
With a resume like that, you'd think they would have signed him up FIRST for those new Miller Lite "Man Law" commercials.
EDIT: I'd be remiss if I failed to mention his entertaining little performance in one of my favorites, "Trading Places." Also, it appears the AP is saying he was 67, while IMDb and Wikipedia say he was 62. Strange there'd be that kind of disparity.
They picked Grant Gustin who was on Glee apparently (not on my viewing list). Guess I'll have to wait and see, that worked for me with Arrow; crossing my fingers on this one. http://m.hollywoodreporter.com/live-feed/glees-grant-gustin-set-as-625751
