The K271 gives what I would call an un-opinionated rendering of movie sound. If you are a film student, or of an analytical turn of mind, you'll probably like the way the K271 lets you listen closely to the sound design of a scene: ah, there's the footfall; oh, I see they put a little bit of street noise just outside that window; hey, I can hear the celing fan turning lazily; whoa, the title theme is playing really softly in the background. It's not called the K271 Studio for nothing: it's a high-quality monitoring instrument.
But if you just want to watch and enjoy the darn movie without deconstructing the sound design for film school, you can get more fun for your money with open headphones, and save the cost of an amp. If you don't absolutely need closed headphones (and it sounds like you don't, for this application), then I'd lean towards the Sennheiser HD595 (the current 60-ohm edition). It is a very good-sounding all-around headphone, it's easy to drive, it has some extra oomph in the bass that makes car chases etc. that much more fun, and it's quite comfortable. And (I just have to say it twice) it's just a really good-sounding all-around headphone.
PS: to echo some of the above posts, I too would recommend an amp with the K271. It tends to sound somewhat lifeless unless well amped. It reveals source deficiencies pretty well too -- if the audio electronics in your receiver/DVD player/TV are not exceptionally good, the K271 will make them sound kind of limp and unsatisfying. Whereas with the HD595, fairly ordinary-level electronics still sound very fun and lively.
