He was superb as Hal Weissman, a completely burnt-out hippie/crazed legendary movie producer who works out of Ted Kazinsky's cabin (which he had relocated to his posh backyard) with "Go Ask Alice" playing in the background, in "America's Sweethearts." It's worth watching the movie for him alone -- he even gets in some dancing! He's hilarious in it. I adore Christopher Walken, and really like his philosophy of life. Whatta guy.
