Is this coming out in theaters or will I have to order the DVD from the internet?
The plan seems to be to show it in theaters at the places where a lot of people seem to want it. In the website I linked there's a map you can go to and add your location to to increase the chance it'll come to a theater in your area.
I think I should point out (to those too lazy to click the link and read the description) that this is a comedy. Which is actually kind of disappointing. Could've been one of those "ridiculous, but could be AWESOME" movies like Cowboys Vs Aliens.
I don't know why you seem to be assuming if someone likes the movie they can't possibly be aware it's a comedy. Depending on the type of comedy it is, I think it could work pretty well. Sure, if it's a bunch of slapstick I'll be disappointed, but that doesn't seem to be the direction they're going in.
