Star Trek, then Night at the Museum.... I feel like I just watched their trailers on cable tv. What allows movies like these to come to campus so quickly?(I'm thinking the answer is likely either my lack of a sense of time or something to do with the industry. Perhaps they were set up from the start to quickly be put up for sale on DVD?)

During the summer the high number of new blockbusters released tend to push films off faster than at other times of year. When Harry Potter opens on 4 of the 12 screens in a multiplex they have to drop something to make room. It also depends on the film. Something like Transformers 2 is heavily front loaded, it will have made about half it's total gross on opening weekend. It won't play more than few weeks first run. It's also a long film so that encourages theatres to drop it as long movies make less money since fewer showings can be done in a day.
On the other hand there are films like Up and The Hangover. Hit kid's films like UP tend to drop down to matinees only and play for a couple months. The theatres like the 3-D ones as they can charge extra. A movie like the Hangover is one of those occasional word of mouth hits that just keep chugging along. Recent examples were Juno and Wedding Crashers. Hangover has had some of the lowest week to week drops in grosses of recent memory. A big action film will typically drop 50-60% in it's second week. The Hangover has been dropping only about 20% a week. I'm planning to play it during Frosh Week but there is a possibility I might not be able to get it by then.

The DVD window is now about 4 months so that doesn't come into play except for the occasional film that's still playing in theatres when it comes out of DVD. Regular readers of this blog will probably be able to guess which studio tends to do this the most...Fox.
