French director Francois Truffaut called it his "favorite American film."
Italian director Michelangelo Antonioni considered it "one of the purest movies I've ever seen."
Kastle, whose first film was destined to be his last, died May 18 at his home in Westerlo, N.Y., after a brief illness, said Tina Sisson, a friend. He was 82.
Kastle is considered one of America's most intriguing one-shot movie directors.
Neither he nor producer Warren Steibel had any filmmaking experience when they set out to make "The Honeymoon Killers," which gained cult status in America and Europe.
The film's original director was a young Martin Scorsese. But Scorsese's filmmaking pace was too slow and he was soon removed. Industrial filmmaker Donald Volkman then stepped in for a time before Kastle took over as the credited director.
