I can't believe RV is coming out on DVD already (August 15th). It entered the theatres on April 28th. 3.5 months from theatrical release to DVD release. That's a real indicator of bad news for the film industry. As a former Hollywood development employee, I can tell you despite all the talk of record weekends, the film industry is in big trouble.

#1 - At $6 a ticket, people will see just about anything just to get out. At $10 a ticket people only want to see something they are certain will be good. This means everyone sees the same movie (Pirates of the Caribbean) and avoids everything else (RV). Hollywood cannot survive on a few monster successes. It needs an even balance of huge hits, modest successes, break evens, and failures.
#2 - When everyone had a 19" TV and a VCR, the movie going experience was always better. When everyone gets a widescreen 50" plasma screen TV with 5.1 stereo all of a sudden the theatre going experience is not so great. With shorter time spans between theatrical release and DVD release, this will only get worse.

The end result is there will be fewer movies made as studios cut back on production deals and studios will take less risks on innovative films and instead churn out the same old thing. Look at this summer, how many movies came out that were original ideas and not a sequel or remake?
