I'll tell you why movie revenue is dropping...
I think Alamo Drafthouse in Austin is doing it right:1. Food & beer/wine served with movie -- convenient and much preferable to overpriced popcorn.2. Cellphones must be turned off.3. They take talking seriously, and preface each film with a strongly (and amusingly) worded statement to that effect.4. No babies allowed except on specified baby nights.5. Creative and fun special events, such as quote-alongs, sing-alongs, live comedy (Master Pancake, which is sort of like live MST3K), movie/food pairings, etc...I pretty much refuse to go to any other theater, and judging by their crowds, they seem to be doing quite well with this formula.
