The Weinstein Co. will give audiences in New York and Los Angeles an earlier look at “St. Vincent” than originally planned.

The Bill Murray and Melissa McCarthy comedy about a curmudgeon whose hard edges are softened ever so slightly by the son of a single mother will debut in the two cities on Oct. 10. That will be followed by a gradual roll out into 25 cities on Oct. 17, before it goes wide on Oct. 24 as originally planned.

Oct. 10 is occupied by the releases of Robert Downey Jr.’s “The Judge” (wide) and Sundance winner “Whiplash.” The weekend of Oct. 17 features Michael Keaton’s “Birdman,” also in limited release.

“St. Vincent” has its world premiere Friday at the Toronto Film Festival as part of what the gathering’s backers have billed as “Bill Murray Day.” The festivities boast screenings of “Stripes,” “Groundhog Day” and “Ghostbusters,” as well as a question and answer session with the elusive star.
