It's that time of year where everyone wants to have the “hap, hap, happiest Christmas” with your favorite holiday movies. Which means you may be asking: How can I watch my favorite Christmas movies? Enter AMC's Best Christmas Ever, a Christmas movie spectacular with over 700+ hours of family friendly holiday movies on-air and online, now through Christmas Day.

Among the titles you can stream is 1989's National Lampoon’s Christmas Vacation. Featuring Chevy Chase, Beverly D’Angelo, Randy Quaid and more, National Lampoon’s Christmas Vacation follows the Griswold family as their holiday festivities go from bad to worse. When Clark (Chase) and Ellen (D’Angelo) Griswold get a surprise visit from their extended family, Clark’s dream of a “fun old-fashioned family Christmas” goes down the sewer (literally! You’ll have to watch the movie). But after a series of hijinks, Clark realizes the true meaning of the holiday. Produced by John Hughes (The Breakfast Club, Ferris Bueller’s Day Off, Home Alone), this Christmas comedy classic is a hilarious reminder that Christmas isn’t about a picture perfect tree and holiday decorations — it’s about the people you spend it with.
