Your Mom says hi...

Braveheart without Tucker present, definitely.
And how could you list guy movies without mentioning Fight Club?
 

damn, you're right. Fight club is more or a mind-fuck movie given the ending, but that's absolutely true.
I'd put that in above Braveheart then, making the Scot 5.5
 

Swingers, the Indiana Jones trilogy, American Pie (works for both genders, but definitely more geared towards men), the Godfather movies and Rudy. wOOt!
 

i define a 'guy movie' by any movie that the average girl would not like. As a corollary, it is a movie that is beloved by engineers (who are almost entirely guys, much to my chagrin). Consequently...

1) The Rock
2) Bad Boys 1 or 2
3) Gladiator
4) Lord of the Rings
5) Any Star Trek movie

The last two are mostly cause I can't name a single girl (and i know engineering girls - the least girly of them all) that likes any of those. I even know one that likes star wars.

I'm also tempted to put Sin City on there, simply cause chicks don't dig hookers killing people with swords. I learned that the hard way when I took a girl to see that movie.

Even though I'm a girl, I think I've got good taste in guy movies. These are not just my top 5 guy movies, but the top 4 are my top 4 movies, period. To be fair, I am an engineering girl, and all of these movies contain a lot of (mostly fake) science.

1) Star Trek: First Contact

2) Terminator 2

3) Goldeneye...
though I love James Bond movies in general and own all of the old school ones

4) Aliens

5) The Rock

And Kev, I have to disagree with you about Bad Boys 2... It fell shamefully short of the first one which was totally awesome.
