Gonna follow M00t's lead since there are plenty of other GREAT movies.
Once Upon A Time In The West (Best showdown ever, Henry Fonda made an
incredible bad guy)
Rollerball w/ James Caan (Disturbing view of future society)
Flight of the Phoenix w/ Jimmy Stewart (what airplane guy doesn't like the premise?)
Dark Blue World 2001 (Czech pilots during Battle of Britain,
See this movie! and let me know what you think of the "bicycle flying")
Enter The Dragon (Yeah, I know. But I'd be just another fat, middle-aged slob if it weren't for Bruce motivating me as a kid. Now I'm a dangerous fat, middle-aged slob
)
Forbidden Planet (a landmark for 50's Sci-Fi)
The Day The Earth Stood Still (ditto)
The Shootist (no comment necesary)
Dark Star (Totally off the wall. "
You are false data"
)
and on and on ....
Oh and
They Live (Street fight between Roddy Piper & Keith David is awesome.
"I came here to chew bubble gum and kick ass... and I'm all out of bubble gum." )
