What's the ultimate Christmas movie?  A new scientific study used 20 different factors to finally put that discussion to bed.

The four main categories they used were:

  1. the number of Christmas references in each one
  2. how they did at the box office
  3. their reviews
  4. and how much of a "festive buzz" they create year after year

Here Are The Top 10:

1. "Home Alone", 1990

2. "Elf", 2003

3. "Love Actually", 2003

4. "How the Grinch Stole Christmas" (the 2000 version with Jim Carrey)
