Bill Murray appears in debut trailer for "St. Vincent"

We're getting a first look at Bill Murray playing a misanthropic war vet in the trailer for the upcoming movie "St. Vincent," which hits theaters Oct. 24.

Directed by Ted Melfi, "St. Vincent" follows a young boy (played by newcomer Jaeden Lieberher) and his divorced mom (Melissa McCarthy) who move next door to St. Vincent de Van Nuys, played by Murray.

Needless to say, Vincent has some issues with nothing left in his bank account as he walks around (sometimes drunk) with a mysterious head wound.

Buzz is building for the film, which also stars Chris O'Dowd and Naomi Watts as a pregnant stripper.
