David Duncan didn't begin to write full-time until the age of 33, in
1946, after ten years of work in government administration and public
services. He began screenwriting in 1953 and started writing
science-fiction movies after one of his SF novels, "Dark Dominion", was
serialized in "Collier's" magazine. His favorite among the sci-fi films
he wrote is
Die Zeitmaschine (1960), "by a
huge margin."
