When it comes to movie titles, it's best to go as simple as possible. To do otherwise would create unnecessary confusion, so just name an object in the movie and keep the syllable count low (People don't like a lot of syllables jumbling around in their head like pinballs). For example: If the movie is about some babies, call it Babies; If the movie takes place in some oceans, call it Oceans; if the movie is about some hilarious married killers, call it Killers; etc. No articles. No mysteries. Just name a noun, possibly pluralize it, and, boom, there's your movie. (Incidentally, if The Hurt Locker had been called Boom, it could have been much more successful.)
