December can only mean one thing: Christmas movies galore! Up this month are plenty of traditional Christmas classics along with a few off-beat ones that will certainly please fans of Mystery Science Theater 3000. In addition to that, every Thursday in December, TCM will be saluting living legend Mickey Rooney by playing 24 hours of his movies, including every Andy Hardy movie and all his pairings with Judy Garland. Speaking of living legends, a new episode of Private Screenings will be premiering this month featuring Liza Minnelli. To celebrate, TCM will be taking two nights to showcase some of the best movies by Liza, Judy, and Vincente. This month’s guest programmer is Eli Wallach, who has made some very stellar choices. Fans of John Wayne will be glad to hear that on December 22, there will be 24 hours of nothing but John Wayne. When New Year’s Eve rolls around, why not bid 2010 adieu with Cary Grant movies all day and Marx Brothers movies all night? And to top it all off, the final two installments of the Moguls and Movie Stars series air this month on the first two Mondays and Wednesdays.
