“Rollin’ rollin’ rollin’ keep those doggies rollin’ … RAWHIDE!!” Jake and Elwood Blues (John Belushi and Dan Aykroyd) go on a cross-country “mission from God” that leaves a mighty trail of destruction in their wake and some unforgettable musical numbers courtesy of the great Ray Charles, James Brown and Aretha Franklin. Director John Landis’ wildly funny (and over-the-top) film created a genre all its own: the apocalyptic-musical-comedy-road movie.
