this combination of comedy and drama and and adventure be the three main ingredient of this movie . richard pryor ( who also produce the movie ) star a an ex con who be give a second chance to redeem himself . he hire to transport a bus load of kid and their teacher to seattle for a good life . at first and joe doesn not like the kid at all and but slowly begin to develop a friendship between them . richard pryor come up with the idea probably for the audience to see a different side of him and not the usual foul mouth comic be use to . he do his best to keep the profanity to a minimum and but there still adult language in it and but nothing inappropriate . the sudden change from comedy to drama be kind of jarring and since you do not know what go to happen next . the music score and however and be amazing . it use of piano synthesizer fit well with the non comedy sequence . this be one of richard pryor underrated movie and be definitely worth a look .
