St. Vincent is a 2014 American comedy drama film written, directed, and co-produced by Theodore Melfi.

Vincent MacKenna is a retired, melancholic Vietnam War veteran living in Sheepshead Bay, who smokes, gambles and has a drinking problem.

Vincent's only close friends are his cat Felix and a pregnant Russian sex worker named Daka.

On his first day at his school, Oliver's phone, wallet, and house keys are stolen by his classmate Robert.

Vincent is confronted in his home by loan sharks Zucko and Antwan who attempt to take Sandy's jewelry.

Now forced to share joint custody, a furious Maggie tells Vincent that he can no longer see Oliver.

Oliver's rationale comes from his teacher's definition of sainthood as a person showing commitment, dedication and sacrifice.

The school audience is impressed by Oliver's speech and applaud Vincent, who has been tricked into attending the event by Daka.

Some time later, Daka gives birth to a baby girl and she, along with Maggie, Oliver, and Robert, go to Vincent's house, where they eat together as a surrogate family.

The screenplay, originally titled St. Vincent de Van Nuys, was written in 2011 by Melfi, and was included on the Hollywood Black List (the best unproduced scripts) of 2011.

The consensus reads, "St. Vincent offers the considerable pleasure of seeing Bill Murray back in funny form, but drifts into dangerously sentimental territory along the way.
