But either way, read this Wired article about Philip K. Dick.

Dick, who died in 1982, was something of a cult figure until very recently. However, once Hollywood started to accumulate some success with his work, he became dramatacally less obscure. He’s the science fiction author who wrote the stories upon which Blade Runner (novel, “Do Androids Dream of Electric Sheep?”), Total Recall (short story, “We Can Remember It For You Wholesale”), and The Minority Report (short story of the same name) were based. There have been others, and there’s more coming.
