Back to the Future - A heavily modified (sic!) De Lorean, crappy Euro-V6 engine substituted by the one-and-only Flux Generator, later on this thing became a multi dimensional airplane...just kidding ;-)
Blade Runner - Loads of great gravitation defying future flying machines
Donnie Darko - Airplane with one-engine-jettisoning-mechanism, although one only gets a view of the fallen-off donkey ;-)
Avatar - Nothing to comment on that, I guess...
Jurassic Park - They let some kind of creature trash an invincible King Air, how realistic... ;-)
X-Men: Great beefed up SR71
Not a movie but a series: FRINGE - Zeppelins and other machines
What else? Schwarzenegger's 6th Sense with the strange Comanche-look-alike-Helicopter
And last but not least the Master: FIREFOX with Clint Eastwood - hint: the book is by far less annoying in the first half and even more stunning in the second half... and the sequel is worth a read, either...
