This trailer is for a movie(?) by Joss Whedon. It stars Nathan Fillion and Neil Patrick Harris. I also spotted Felicia Day, the red-headed girl from The Guild. It says coming to a computer soon... sadly that probably means exactly that, it's not a theatrical movie. :(
But it's by Whedon, has a cute red-head, and Nathan Fillion is getting work, so it's all good.
