25 is a bit much for me right now 'cause I'm headed out the door. But here's ten.
1.) Star Wars.
2.) Return of the Jedi.
3.) Revenge of the Sith.
4.) All About Eve.
5.) Avatar.
6.) Anastasia (Yul Brenner version.)
7.) Kung-Fu Panda (very cute and entertaining).
8.) War of the Worlds (older version from the 50s.)
9.) "The X-Files Movie" (1998).
10.) Kenneth Branaugh's version of Hamlet. (and also his version of Henry V.)
I also just recently saw a great science fiction movie from the 70s called "The Omega Man" starring Charlton Heston. This is the same story as the movie "I Am Legend" which recently came out starring Will Smith. (There was also a version from 1964 starring Vincent Price, called "The Last Man on Earth." - They're all based on a novel called "I Am Legend" by someone named Richard Matheson which has received a lot of attention.)
Anyway I thought the Charlton Heston version was VERY good! The Will Smith version (i.m.o.) didn't really capture the emotional impact of the story. The 1964 version was also pretty good, for similar reasons. But Heston's version blew me away; I felt that it was VERY well-done!
