Night on Bald Mountain (Mussorgsky), The Planets (Holst), and Ride of the Valkyries (Wagner) are all pretty badass but often get used in movies, game trailers, even ads without being named.
EDIT: Everyone likes links, ja?

Features heavily in the beginning of 2001: A Space Odyssey.
That movie has some other greats like Blue Danube Waltz by Strauss.
One, dude just played an instrument in the lower register. He fucked up. I quit trombone after a year in (small) part because what's the fun in setting the bass line?
Two, it seems like Canon was sort of "rediscovered" in the late 1960s and the people just absolutely fucking loved that chord progression and pop musicians and their producers were no exception.

Everyone recognizes Erik Satie’s Gymnopedie no 1.
