Even though I'm a huge Rodney Dangerfield fan, I never had the chance to see this film until today since it was in limited release theatrically and the DVD is surprisingly hard to find. Now I know why: the flick just isn't any good. Dangerfield tries his best, but he can't save the uninspired directing (this was director Harry Basil's feature debut and it shows), poor production values, and sluggish pacing. The supporting cast of the usually reliable Annabelle Gurwitch, Robert Davi, and Charles Fleischer is disappointing with each given little to do. However, the first twenty minutes or so are quite funny with Dangerfield's signature quips popping up almost non-stop. Once Dangerfield starts singing, the viewing experience becomes a drag. The 4th Tenor is easily Dangerfield's worst. Basil also directed Dangerfield in Back by Midnight,a much better collaboration between the two. 3/10
