AMSTERDAM, Netherlands -- George Sluizer, the Dutch filmmaker who directed River Phoenix's last movie, "Dark Blood," has died at age 82.

Organizers of the Netherlands Film Festival and the Berlin International Film Festival said Sluizer died Saturday "after a long illness."

In a career that spanned five decades, Sluizer's most celebrated work was probably the 1988 thriller "Spoorloos," or "The Vanishing," about a man's quest to find out what happened to his girlfriend after she disappeared without a trace during a stop at a gas station.

"Dark Blood" was two-thirds complete in 1993 when Phoenix died of a drug overdose aged 23. Years later, Sluizer began editing an altered version of the film, which aired in 2012.
