River Phoenix last movie is finally complete after 20 years since the actor died. Phoenix's last movie, "Dark Blood" was salvaged by director, George Sluizer, by piercing the existing footage with voiceover.

River Phoenix last movie was interrupted by the actor's sudden death in 1993. Filming for "Dark Blood" was scheduled to be completed 10 days before Phoenix was found dead at 23.The cause of his death was never confirmed, however, he was suspected to have died from a drug overdose.

"I found him a remarkable young man," Jonathan Pryce, co-star in "Dark Blood," told reporters after a press screening in Berlin.

"I can't believe now looking back that he was only 23 at the time, a kind of old head on young shoulders. He was absolutely delightful and wonderful to work with"

Pryce continued to say that he never knew Phoenix was using drugs during the filming of his last movie.

"In all the weeks we were together in Utah ... at no time did I experience him using drugs or abusing drugs in any way, shape or form. I'm not a drug user myself but I'd have known. It was a time in his life when he was very committed to not using drugs. I loved him a lot and I love his memory."

The journey to bringing "Dark Blood" together was certainly not an easy one. The Dutch filmmaker, Sluizer, struggled with 25% of the film's footage missing and also with sound and image mismatching. However, Sluizer, who is now 80 years old, managed to readjust the script and use voiceover to explain missing action.

Reuters reports that the the effect the film creates is "surprising coherent." However, Sluizer is not sure if a wider audience would be able to view the film because a deal has yet to be made with the company holding the rights.

"They are very tough," Sluizer said. "They are billionaires, money market people apparently who by mistake I would say have in their stock ... a film, and they don't care about movies and they don't care about culture, they care about money."

Sluizer also added that Phoenix's younger brother and actor, Joaquin Phoenix, gives the filmmaker his blessing. However, the family is not participating in the release.

"The relationship is that the mother of River wished us the best with the film."
