Hollywood Walk of 'Frame' GalleryInstead of 'Walk of Fame'... get it? *sigh..*
LocationHollywood Studio, Walt Disney Studios Park. There are a few options, either beyond the berm of STT, next to CinéMagique or - the best option - right in the middle of Place des Stars as part of Theatre District (see number
2 on this map).
The StoryThe moviemakers of Hollywood are putting on a special art show of rare and unique concept art from classic films. This is a 'La Cabane' or 'Nautilus' for the Studios, an indoor gallery of concept art and storyboards from the latest and greatest Walt Disney Studios films.

The Pirates of the Caribbean trilogy, Chronicles of Narnia and more. There could even be a spot at the end for constantly changing art from the latest upcoming films. Infact, the whole walkthrough would be easy to change with every new film and the theme is wide enough that it could also include real costumes and props to go alongside the artwork. Those windows on STT where you see the real movie costumes are great, but it'd be nice to get more than a split-second to see that stuff.
The concept art on the new Prince Caspian website inspired this:

http://www.narniaweb.com/gall/3184.jpgA lot of people might think the crew just turn up and start filming, they don't realise even live action films have a lot of artwork and storyboarding behind them. This attraction would be a cheap but very interesting filler, a Hollywood sister for Art of Disney Animation.
The exterior would be a cross between these two old movie palaces, which have a styling that almost resembles classic picture frames. The theatre would have been out of operation for quite some time, but now running as a gallery. It could fit into the middle of Theatre District. Maybe the walkthrough could lead you through the various areas of a movie theatre, from the lobby to the projection room?

You'd step in right off the street, although maybe some red rope could cordon off a section if it gets busy.

If Hollywood allow it, they could even start their own Walk of Disney Fame outside, honouring the winners of the Disney Legends awards with a permanent tribute in the park.
Since we're getting ambitious, why not actually have glass in those large windows at the front and open a top floor restaurant, like Walts? This could finally give the studios some table service. If it was build in the middle of Place des Stars, you'd have an amazing view across to Tower of Terror. This would be a serious earner, and would support the building of the gallery below.
