Jalopy represents the first Bowery Boys film to be released by Allied Artists, though in essence it's still a Monogram "B"-picture. It all begins when Sach Jones (Huntz Hall) develops a new fuel formula that will enable a racing car to go around the track in 11 seconds! Sach's pal Slip Mahoney (Leo Gorcey) uses the formula to win several jalopy races, thereby allowing sweet-shop owner Louie (Bernard Gorcey) to pay his debts. Gamblers try to muscle in on the Bowery Boys' winning streak, but to no avail. On the day of the obligatory Big Race, Slip is forced to enter his jalopy without the precious fuel. At the last minute, Sach arrives with a new batch--which only works when the car is shifted in reverse! Heavily reliant upon stock footage from the concurrently produced Allied Artists feature Roar of the Crowd, Jalopy is a typically nonsensical Bowery Boys entry, right down to the surreal climactic gag. ~ Hal Erickson, Rovi
