Not to gloat, but I have a pass to see The Simpsons Movie tomorrow — that is, a full day earlier than the general public. In looking at film's title on the ticket itself, however, I noticed its verbal awkwardness.
Being the translation of the TV show The Simpsons into a film, it poses a problem. The "the" at the beginning of the show's title — which, in my experience, is more often pronounced, as opposed to just saying "I'm watching Simpsons" — has to vanish. Though it's technically correct if you're speaking the title as it's used on the show, you should probably refrain from calling it The The Simpsons Movie, even if it is The Movie version of The Simpsons. And you sure as hell can't say The Simpsons Show Movie or The Movie Version of The Simpsons or even The Simpsons' Movie. I guess you could just treat the title The Simpsons like it's a unit, modifying Movie, but even then I think it's curious that the internal italics of the original TV show title get absorbed by the italics of the movie title when the TV show is ostensibly being referenced in the movie title.
It would have been so much easier if they just called if The Simpsons: Viva Rock Vegas.
