"Jack Butler" (Michael Keaton) just got laid off from his car building job, so his wife (Terri Garr) takes a job as an executive at an ad agency with a major account with a tuna company.
Now, with roles reversed, "Jack" has to stay home, take care of the three kids and become "Mr. Mom."
This movie was a big hit, if I remember correctly. And it is filled with some good laughs, but not a lot. The majority of the laughs come from "Jack" doing things for the first time, like food shopping and trying to multitask chores. Most of the jokes come from physical comedy that Keaton handles pretty nicely. "Caroline" (Garr) has some comedic moments as she is at work, but they are probably light chuckle worthy.
As for the supporting cast, they are not completely developed. They are, however...
