well i know its not "all of the above", which seems to the popular pick right now.
the egyptian theater is older than the chinese so #2 can't be true.
i'm a big disney buff and as any self-respecting disney annual passholder knows, they're currently in the process of a major reconstruction of disney's california adventure. the entrance will be rethemed to 1920s hollywood, sort of a juxtaposition to main street over in disneyland. the big landmark at the end of this street will be the carthay theater, which is where snow white premiered. so not all premieres happend on hollywood blvd even after the 1920s.
the carthay was on san vicente, near where park la brea and the grove is at now - fairfax district. which reminds me of another notable theater which was also in the area... the pacific theater? it was the iconic art deco theater that burned down, located where a park now sits next to the grove. i know this also because of disney -- the main entrance of the disney mgm studios in orlando is styled after the theater.
was fairfax the original theater district? this maybe eliminates #3?
so if 1,2,3 are all false, that leaves #4, #5, or none of the above. given that #4 is so specific, i'll have to go with that one!
