In Home Alone, what line from a gangster movie does Kevin use to scare Harry?

In Home Alone, Kevin uses “Keep the change, ya filthy animal” from a fictional gangster movie to scare Harry.

Kevin McCallister plays the gangster film on a television set while Harry and Marv attempt to break into his house. The recording is not a genuine old movie; it is a specially created black-and-white clip titled Angels with Filthy Souls, made for Home Alone as a parody of gangster films.

The line is therefore spoken by a character inside Kevin's staged television trick, not by Kevin himself. A related phrase appears in the sequel's fictional film, Angels with Even Filthier Souls, which is why the two quotations are sometimes mixed up.

Home Alone was released in 1990, directed by Chris Columbus and written by John Hughes. Macaulay Culkin played Kevin, and the film became one of the most successful family comedies of its era.
