Like Father Like Son was made at the height of Kirk Cameron's bubblegum popularity as teen idol, courtesy of his television series Growing Pains which was dominating the ratings in 1987. Cameron was just getting into his fundamentalist religion kick so the script couldn't be too naughty.
As it is it's a mildly amusing comedy of the Freaky Friday vein, only this time it's a father and son, Kirk's father in this case being Dudley Moore. Kirk's your typical teenage kid, just looking for a good time and not too serious. Moore is a very serious and respected surgeon who would like to be the new chief of staff at his hospital to replace Patrick O'Neal's whose recommendation on a replacement will probably make or break a candidate.
Kirk's got some troubles of his own in the form of shapely Camille Cooper who's hitting on him. She's the girl friend of jock Micah Grant who hates Kirk and his friend Sean Astin.
In fact Astin's archaeologist uncle is the cause of all the problems that Moore and Cameron face. The uncle Bill Morrison has come back from a dig at the Navajo reservation with a body transference medicine that Astin thinks would be worth a few laughs, even experimenting with a dog and cat on it. But when the maid thinks it's a condiment and Moore and Cameron use it on the spaghetti, strange things happen.
Each lives about 36 hours in the other's bodies and the other's lives and generally make a mess of it. If you've seen both versions of Freaky Friday you've got a general idea of what's going to happen.
The film did reasonably well at the box office though it failed to make Cameron a movie star. That didn't happen until Kirk started playing on the Christian film circuit. Moore and Cameron and Astin work well together and it's still mildly amusing.
