I too like movie watching using headphone.
My favorites are Sony SA3000, HD800, Sony MA900, Audio Techica AD700, AKG K501. Please note that the list are not in order, i just listen to whichever my mood drives me.
I tried K70x (K702 to be exact), i think it is very nice for movies too. I tried k712, but i think it is too warm for movies.
