Probably one of the tamest R-rated movies ever. THe only reason it's R is because of one scene at a car rental place where Steve Martin just swears at a woman and uses the f-word frequently. It's used about 15 times in one minute. There's one scene that might be scary for little kids(when they are in the car crash), but other than that, the rest of the film is PG material.
This is a classic for sure. I mean I saw this when i was twelve and theres only one scene that is really bad were the F-word is said like over ten times in less then a minute. Other then that your kids should be agble to see this.
