As of 31 March 2025, 12 sci-fi feature films have been made based on his short stories and novels, plus another two sequels that expand on a setting he established (2003's Screamers: The Hunting and 2017's Blade Runner 2049.

The most successful films based on the works of Philip K Dick are Blade Runner (1982), based on his 1968 novel Do Androids Dream of Electric Sheep?; Total Recall (1990, and remade in 2012), based on Dick's 1966 short story "We Can Remember It for You Wholesale"; and Minority Report based on his 1956 novella The Minority Report.

Dick's total narrowly edges out prolific American novelist Michael Crichton, author of Jurassic Park and The Andromeda Strain among others, whose science-fiction works have been adapted 11 times. Other frequently adapted authors include H G Wells and Mary Shelley (whose place in the top ten is guaranteed by the many adaptions of Gothic classic Frankenstein).
