(i'm probably going to get smashed on by pubikhair)
the only reason u get "smashed" is cos u ask retarded questions.
the answer to this one is "how effing limited is ur knowledge of film that u seriously believe for a second that sum jerk, almost 100 years after cinema was invented, was the first to think of telling more than one story at once????"
read a book, son, check other sites on the interweb, parallel/intertwining stories was one of the greatest developments in cinema history. i mean, the level of ignorance in ur questions is just mind boggling.
there must be so little going on up there that u make this guy..
look like a genius.
