Tom Hanks is a compulsively fastidious detective who winds up with a large, ugly, drooling, and destructive dog that happens to be the only eyewitness to a murder. Needless to say, it proves to be a match made in heaven, and dog slobber enthusiasts (as well as fans of dog farts) will have a field day. Everyone else will have to settle for a formulaic cop comedy that has Hanks but little else. Roger Spottiswoode directed from a screenplay by many hands (Dennis Shryack, Michael Blodgett, Daniel Petrie Jr., Jim Cash, and Jack Epps Jr.), and Mare Winningham and Craig T. Nelson costar. (JR)
