I read that "Speed Zone!" is a semi-addition to the "Cannonball Run" movies; I don't know those at all, so I just have to take the movie at face value. It's basically another flick in the wacky race genre - others include "It's a Mad, Mad, Mad, Mad World" and "The Gumball Rally" - a litany of silliness for silliness's sake. I didn't derive any hidden meaning or anything (even "IAMMMMW" was all about greed). Totally pointless, I guess. Sort of an excuse to have a bunch of stars. There were some funny scenes, but not enough to merit any real recognition. The cast members have all done better than this. Starring John Candy, Donna Dixon, Peter Boyle, Shari Belafonte, Tom Smothers, Dick Smothers and Brooke Shields.
