I’ve often wondered why a lot of Movie Posters will have a slogan to the effect of “Only in Theatres” or “Only at the Movies” on it, when clearly this isn’t the case- most (if not all) movies will get a DVD release not all that long (3-6 months, IIRC) after they’ve finished their run (although I have seen rare cases of films coming out on DVD while they’re still finishing their theatre run).
So what’s the rationale behind this? The fact they’re advertising the movie on a big poster at the cinema should pretty obviously indicate the film is getting a cinema release- so why mention that as a separate slogan?
