In an ersatz Stone Age, the King orders all single males to marry or be banished -- or worse. A husky caveman known as the Mighty Giant (Oliver Hardy) and Twinkle Star (Stan Laurel), an effeminate warrior wannabe, compete for the hand of Blushing Rose (Viola Richard), daughter of Ye Aged Saxophonus (James Finlayson). The two Cro-magnon rivals match wits and strengths in a series of grueling cave-times contests. This leisurely improvisational vehicle was actually a step backwards for Laurel and Hardy at this particular time. After solidifying themselves as a team just months before, they were now back to playing less classical buffoons (although Hardy mostly manages to stay in character), and mostly apart, as part of the Hal Roach Studios comedy stock company. In fact Roach himself was the ghost director of most of the film, which was withheld from release until 1928 when the two comics were gaining global favor as the hottest team in comedy. Flintstones-style anachronisms abound, and the title is a reference to the local elephants flying south (via cartoon animation) for the winter(!).
