James Caan isn't known for his comedy roles in Hollywood but, according to Robert Duvall on 'Late Night' (Weeknights, 12:37AM ET on NBC), 'Jimmy' Caan is one of the two funniest guys he knows. He and Duvall remain close friends after all these years, which could help Jimmy Fallon get Caan on the show.

When Duvall found out Caan had never appeared on Fallon's 'Late Night,' he told Fallon, "Call him up. Get him on the show." Apparently, Caan is in New Zealand "complaining" on the set of a new movie, so he'd even have something to promote. Maybe Duvall will convince his buddy to stop by.

Then Fallon could find out first-hand how funny Caan is. According to Duvall, Bill Murray is the other funniest guy he knows, so maybe Fallon could have them both on and compete in some kind of "funny-off." You know how Fallon loves his games!

Bill Murray was on 'Late Show With David Letterman' (weeknights, 11:35PM ET on CBS) tonight, and he had his leg in a sling and his foot up on Dave's desk.

That would be interesting enough, but even wackier was his sparkly purple top, striped shorts, and Russian snow hat. He told some story about 'Ghostbusters,' but frankly, we can't even remember what it was.

It's beginning to look a lot like Christmas over on Moviefone's Inside Movies.

That's because the busy elves over there have re-imagined classic Hollywood movie posters as inappropriate holiday movies. Hey, you looking at the Christmas-themed movie poster for 'Taxi Driver'? Then we have Christmas classics re-imagined as action flicks. Take a gander at Rambo as Scrooge.

Also on Inside Movies, Ivan Reitman confirms that there will be a Ghostbusters 3 and that Bill Murray and Sigourney Weaver are on board -- but not in a way you'd might expect.

Radner. Louis-Dreyfus. Poehler. Fey. Shannon.

Suffice it to say, the number of women who became famous on Saturday Night Live before graduating to solo success is few and far between. Sure, Gilda Radner can be considered a pioneer in the art of sketch comedy. And Julia Louis-Dreyfus undoubtedly honed her comedic skills before becoming a sitcom icon on Seinfeld. And, yes, Tina Fey can easily be considered a heroine to comedy nerds everywhere who have witnessed her climb from Weekend Update anchor to Mean Girls scribe to single-handedly decimating the vice presidential chances of one certain gun-wieldin', six-pack-totin' Alaskan governor.

But, sadly, the number of men who left Studio 8 for the superstardom of Planet Hollywood (not the theme restaurant) easily outnumbers the ladies. For every Amy Poehler, there's a Will Ferrell. And a Bill Murray. And a Mike Myers and Eddie Murphy and Adam Sandler (although, to be fair, there's also a David Gary Kroeger, A. Whitney Brown, and Charles Rocket for every Melanie Hutsell, too). (And for the record, no, you shouldn't recognize those names.)

Well, that was a little strange... and maybe a little unnecessary. All right, it was definitely unnecessary. I wasn't quite sure how they were going to work out these Thursday election specials, because even though they called it "Weekend Update Thursday", I didn't believe they were just going to show a twenty-some minute long "Weekend Update" segment. As it turned out, the special consisted of one cold open and the rest was "Weekend Update." This is where I got super-confused. Half of these jokes had absolutely nothing to do with the election, leaving me to wonder if there is anyone out there that could not have waited until Saturday night to hear the relevant jokes. I don't think anyone's going to forget the election or the economic crisis any time soon, let alone by Saturday.

As AOL Television continues their look at the 50 Best TV Comedies -- Ever with numbers 30-21, we here at TV Squad are also looking at television comedy, but with a slightly skewed difference. Last week, we took a look at the numerous stand-up comedians who became sitcom stars. In this installment we look at one particular TV comedy that made stars out of a number of actors and actresses.

I'm talking about NBC's Saturday Night Live. Since its premiere in 1975, the late-night sketch show has given us a slew of actors and actresses who have made the move onto both the big and small screen. Sometimes the move was towards more comedy, sometimes it was a switch to more serious roles, other times it was a little bit of both. And, while many of those who made it are still in the public eye these days, some of the greatest of those who came from Studio 8H had their careers snuffed out way too early.

The amount of those who rose to the top varied from cast to cast. Some casts, like the very first one, produced a whole slew of talent who went on to bigger and better things. Others, like the first casts from 1980-85 and the mid-1990s, produced very little in the way of big stars.
