As Frank Capra’s 1946 holiday classic It’s a Wonderful Life shows, a lot of things wouldn’t have happened in the fictional town of Bedford Falls if suicidal businessman George Bailey had never been born. In the real world, however, Bailey’s nonexistence might have brought about even more dire consequences: The lack of the holiday classic film genre altogether. In such a nightmarish alternative universe, the AFI Silver Theatre and Cultural Center’s three-film “Holiday Classics” series—which also includes Bob Clark’s A Christmas Story and Brian Henson’s The Muppet Christmas Carol—would likely feature Silent Night Deadly Night and Jingle All the Way instead. And every time a bell rung, Sinbad would get another role in Hollywood. The series runs to Tuesday, Dec. 25, at the AFI Silver Theatre and Cultural Center, 8633 Colesville Road, Silver Spring. $9.75.
