Yes. You can play lots of Quicktime files under Linux with
quicktime4linux.

The trick is the Sorensen codec Quicktime files that everyone seems to
like. You can play Sorensen on Macs and Windows, cause that's all Sorensen
has licensed the codec for.

You can use Codeweaver's Crossover plugin to run the Windows version of
Quicktime as a plugin to your favorite browser. Works well enough for
apple.com/trailers. The $20 was worth it, IMHO.

"OK, I've just about had my FILL of riddle-asking,
quest assigning, insult throwing, pun hurling,
hostage taking, iron mongering, smart arsed fools,
freaks, and felons that continually test my will,
mettle, strength, intelligence, and most of all,
patience! If you've got a straight answer ANYWHERE
in that bent little head of yours, I want to hear
it pretty damn quick or I'm going to take a large
blunt object roughly the size of Elminster AND his
hat, and stuff it lengthwise into a crevice of your
being so seldom seen that even the denziens of the
nine hells wouldn't touch it with a twenty-foot
rusty halberd! Have I MADE myself perfectly CLEAR?!"
