At this point in his career, Bill Murray has become such a master of translating his own bemusement into the amusement of his audience that you could probably put him in a 30-minute infomercial about crop futures and still get a few laughs.

"Ladies and gentlemen," you can hear him saying, with just the faintest trace of a smirk at the corners of his mouth, "I'm here to talk to you about corn."

Murray established himself in the 1970s and '80s as a comedian with a rare combination of sarcasm, smarminess and outright slapstick, mellowed by a disarmingly self-deprecating edge. He earned his fame on "Saturday Night Live" and in blockbuster comedies like "Ghostbusters," "Caddyshack" and "Groundhog Day." After fading a little in the '90s, an older Murray reestablished himself as an icon of minimalist cool — the comedic patron saint of indie films — with his roles in movies by Wes Anderson, Jim Jarmusch and Sofia Coppola.
