Plenty of others I'll happily watch before Christmas to come too....
Also watched Meet the Parents which whilst not a Christmas film by any stretch gave me that 'down time between Christmas and New Year' feeling, which I guess a Christmas film is meant to help you feel
A perfect Christmas film, which they never put on for some reason, is 'Little Lord Fauntleroy'. It stars Alec Guinness, Eric Porter, Connie Booth who played Polly in Fawlty Towers, and was made in 1980.
