I agree a broad, bottom up approach will be required if we want to see the game changed. I also think that anything (movies or reality shows) that focuses on the money matches or gambling side of it won't help sponsorships down the road. It's fun to romanticize that (very real) part of the game, but that's all the general public thinks about when they think about pool. I have four ideas that could help:
1. Agree with Petros Andrikop about the European model, forming a premier league and allowing other upper level leagues/tours to feed into it. If you qualify to play premier league, you have to stay qualified...points drop, you drop and have to re-compete to get back in next season. Someone would have to sponsor/act as governing body for this, but once it's up and established, should draw bigger sponsorship.
2. The reality show angle is a great one, IMHO. Do it on SPIKE TV. Joe Rogan could pitch it and host it, since he's been involved in MMA related reality stuff and is a player, too...Just like MMA and that show with the boxers, you'd have two teams of high quality amateurs, male and female, each team coached/mentored by a HOF player (I'd pick Mike Segel and Nick Varner, as their careers span a couple of generations of players; although you could pick coaches that have a "history" for more color). Each team lives in their own Big Brother house, lots of shots of practice, woofing and sweating out their upcoming match. Coaches talking about the game, the prospects of their team, some anecdote stuff. Players get eliminated in race to nine 9 ball. Could have weekly cameos by top players stopping by. The winner gets sponsored and seeded in the next U.S. Open...his/her matches in the Open get covered as part of the show. You have to get the audience to care about their "favorite" player, to keep pulling them in each week to root for them, or it won't work. Compelling back stories won't hurt, either.
3. Like snooker in the UK, we really need to use the power of the compelling characters that we have. A documentary on Showtime or HBO...follow Early Strickland around for three/four months, everything from practice, appearances, regional tourneys, culiminating in one of the big tourneys. He's far and away the most compelling guy in our game to do a serious documentary on...lots of interview/comments from Earl about his game, the game in general, the fans, other players, etc.

Could get a lot of commentary on Earl from a lot of sources. Now's a good time to catch him, as he's reinventing his game.
4. Would be nice to have another "Color of Money" come along and get the next generation (and some of us older guys) excited about the game. I think I'd personally like to see something a little less dark or less about gambling, though...maybe a bio pic directed by and starred in by Clint Eastwood on the last 15/20 years of Irving Crane's life...a guy pushing 70 wins a World title is about as compelling as it gets, and it would focus more attention on the tournament part of game. Could have lots of flashbacks and as much star power as you want, depending on the script.
