Top 10 Christmas Films (in no particular order):
It's A Wonderful Life, 1946 – When a man tries to commit suicide on Christmas Eve, a guardian angel shows him what his hometown would be like if he had never lived. You will cry.
Die Hard, 1988 – New York policeman John McClane attends the company Christmas party of his estranged wife, who is a businesswoman in Los Angeles. Terrorists threaten to ruin the festivities. Some of the best one-liners in film history.
Miracle On 34th Street, 1947 and remade in 1994 – A department store Santa restores a little girl's faith at Christmas. A true classic.
Home Alone, 1990 – Kevin McCallister, 8, is mistakenly left behind when his family flies to Paris for their Christmas vacation. He then cleverly fights some bad guys in some very funny moments. Who doesn’t love this film?
Bridget Jones's Diary, 2001 – Maybe not technically a Christmas film as such, but it has a great Christmas scene with Colin Firth in one of the ugliest and most embarrassing festive jumpers ever known to man.
Love Actually, 2003 – Tells the story of eight couples dealing with their love lives in loosely interrelated plots during the festive season in London. Much better than other films of its type like Valentine's Day and New Year's Eve.
Trading Places, 1983 – A rich man and a poor man switch classes as part of a social experiment during the festive season. Great comedy.
National Lampoon's Christmas Vacation, 1989 – The Griswold family plans turn to disaster at Christmas. There's a reason why this film is on television every Christmas.
The Gremlins, 1984 – Careful what gifts you give people at Christmas! Every child of the 80's can recite the Gremlin rules: keep it out of daylight; never get it wet; and never, ever, feed it after midnight.
Giant, 1956 – Although not technically, a Christmas film, there is a memorable Christmas scene. This was James Dean's last film before his tragic death, and with his character aging into his senior years, the film shows audiences what might have been if the legendary actor had lived a longer life.
Notable mentions, some of which aren't technically Christmas films either, but have Christmas scenes in them:
Stepmum, 1998 – A memorable family Christmas scene. Susan Sarandon is amazing in this film.
Citizen Kane, 1941 – A young Kane receives a sled as a Christmas gift. How could I not mention one of the greatest films ever made?
Donnie Brasco, 1997 – An FBI agent infiltrates the Mafia. In one scene the characters celebrate Christmas by exchanging cards stuffed with money.
Batman Returns, 1992 – Batman fights the Penguin, Catwoman, and a corrupt industrialist during Christmas.
The Godfather, 1972 – Christmas in 1945 is the backdrop for several murders by the Mafia. Still one of the greatest films ever made.
Kiss Kiss, Bang Bang, 2005 – A crook poses as an actor and gets tangled up in a crime during a Christmas setting. Hilarious. Val Kilmer and Robert Downey Jnr are fantastic!
Goodfellas, 1990 – In one scene the mobsters celebrate Christmas after pulling off a heist.
Little Women, 1933, 1978 and 1994 – Includes scenes of the family during Christmas. One of the greatest novels ever written and the films do it justice.
Mean Girls, 2004 – A teenage outsider learns about school cliques. Includes a scene where girls sing and dance to Jingle Bell Rock. Even men like this teenage romantic comedy.
Lethal Weapon, 1987 – A young, depressed policeman partners with a veteran officer to solve a murder during the Christmas period. One of the best buddy action films.
L.A. Confidential, 1997 – While investigating a Christmas Eve massacre, three detectives uncover corruption.
When Harry Met Sally, 1989 – Has several Christmas and New Year's scenes. It also happens to be one of the best romantic comedies of all time.
I'm sure I've missed some great films, so please add your suggestions, and have a very Merry Christmas :)
