HELP! Comparison: "The exorcist" (1973) and "I Am Legend" (2007)

One is a horror movie, the other is a horrible movie.

similarity: they are both movies

differences: too numerous to list here

I still have to be in a well lit room full of religious relics and NO WEEJEE BOARDS when I watch "The Exorcist ". SCares ths crap out of me and the kids(my wife wont watch it, course she wont watch the THREE STOOGES)

Will Smith is in both of them, except for The Exorcist.

Hmm.. Thanks guys.

both have 7's in the year they were made.

There are 34 years between the making of these movies, and 3 + 4 = 7.

Coincidence?

I think not.
