Hollywood Themed College Ball?

My daughter had a Hollywood themed dance at her school. She's the art teacher, so she ended up doing most of the decorations as art lessons. She bought a lot of foam board. You can get it at the Dollar Tree Store for $1 each. They cut out "film reels" with a razor knife and then spray painted them black. They also cut out "masks." These were like the ones they always show for art or theater. They spray painted these silver. They used black and silver balloons all over. They cut out a big "HOLLYWOOD" sign by cutting individual letters from each foam board. I can't remember what else they did, but just anything you can think of that reminds you of Hollywood. They rented a red carpet for guests' arrival. I don't know how you could make your own red carpet, but maybe you could come up with an idea. Hope this helps. Just try and let your imagination go wild!
