Rockin' in the Rockies is a musical western full-length movie starring the Three Stooges (not to be confused with their 1940 short subject Rockin' Thru the Rockies). The picture was one of the Stooges' few feature films made during the run of their more well-known series of short subjects for Columbia Pictures, although the group had appeared in supporting roles in other features. It is the only Stooges feature with the act's most famous line-up (Moe Howard, Larry Fine, and Curly Howard) in starring roles. (thetvdb.com)
