A war veteran with many vices becomes the unconventional babysitter of a 12-year-old boy in the first trailer for St. Vincent. When Vincent (Bill Murray) realizes he's flat broke, he agrees to babysit Oliver (Jaeden Lieberher), the 12-year-old son of his new neighbor Maggie (Melissa McCarthy). Watch as Vincent introduces Oliver to the wonderful world of gambling and drinking in the first footage for this upcoming comedy, co-starring Naomi Watts, Chris O'Dowd, Terrence Howard and Nathan Corddry.

Maggie and her adopted 12-year-old son, Oliver, move next door to war veteran Vincent, but when Oliver gets locked out after school one day, Vincent allows him to stay at his house until his mom gets home. Because he has bills up to the ceiling and is desperate for cash, he tells Maggie he'll babysit Oliver every day after school. Vincent then introduces Oliver to his lifestyle, including gambling, drinking, and his relationship with a Russian prostitute.
