Melvin and Verdell
As Good As It Gets (1997)

In the 1997 rom-com, Jack Nicholson plays Melvin Udall, a successful author with extreme OCD. Against all odds, though, he bonds with his gay neighbor's dog, Verdell, a Brussels Griffon who loves bacon. "Don't you be like me. You stay just the way you are!" Melvin tells him.
