Sounds interesting. I haven`t heard of the others, yet (besides Manderlay), so Id be pleased with a write-up. 
And have fun at the festival!
Today I`ll watch the last film in my hometowns "Festival" of some sorts (only eleven films, cornered by 15 classics) and I`m in a good mood: Goodbye, Dragon Inn (Tsai Ming-liang / Taiwan / 2003).
