The film, which sees late actor Philip star as the leading man, has been given a US release date of 9 May.
Philip, who died unexpectedly on 2 February, had filmed God's Pocket in his native city, New York, as was promoting the movie in the weeks before his death.

Directed by Mad Men actor John Slattery, God's Pocket sees Philip star as Mickey Scarpato, a man who tries to cover up the accidental death of his stepson.
The film, which was screened at Utah's Sundance Film Festival in January, also stars John's Mad Men co-star Christina Hendricks, John Turturro and Caleb Landry Jones.
The news of God's Pocket's release date comes a week after Philip's autopsy results were revealed.

The 46-year-old actor, who was found dead in the bathroom of his New York apartment, passed away as the result of combining acute amounts of heroin, cocaine, amphetamines and psychoactive drugs such as Librium.
A spokeswoman for the New York City medical examiner confirmed that Philip's drug overdose had been ruled accidental and law enforcement officials added that the father-of- three was found with a needle in his arm and at least 50 empty packets of heroin in his Manhattan apartment.

Philip, who won the Oscar for Best Actor after his role in 2005 biopic Capote, was found by his close friend David Katz and his personal assistant Isabella Wing-Davey after failing to pick up his three children from partner Mimi O'Donnell.
The actor's absence caused costume designer Mimi to call David to find out where he was. David and personal assistant Isabella then went to Philip’s apartment where they found his body. The Hollywood star had previously revealed that he had struggled with drug addiction since his student days and reportedly checked into rehab last May after 23 years of sobriety.
Philip, who left behind three children, made one of his last public appearances at the Sundance Film Festival while promoting God's Pocket.
