The final film of troubled star RIVER PHOENIX, who died at age 23 from a drug overdose, will finally be released, The ENQUIRER has learned.

Eighteen years after the tragic death of River Phoenix, director George Sluizer says he will finish Dark Blood, the horror flick River was lensing when he died Halloween night 1993 outside the Viper Room in Los Angeles, The Hollywood Reporter revealed.

Sluizer then took the original Dark Blood footage after Phoenix’s death and kept it hidden, fearing the film elements would be destroyed in the wake of the tragedy.

But now, the director has re-edited the raw material and is convinced with some film magic including a narrative voice over, he can finally release the film next year.

Sluizer told THR he plans to ask Joaquin Phoenix, River’s brother, to voice the flick’s narration as River’s character.

“The voices of both brothers are very much alike,” the director said.

According to Dark Blood insiders, in the film, Phoenix plays hermit holed up on a nuclear testing site in the desert as he waits for the end of the world.

As the world sits on the edge of the abyss, he enters into a bizarre three-way with a jet setter and his wife in an existential fear fest.
