Filmed in "Fox Grandeur," an early widescreen process, Happy Days was the immediate follow-up to Fox Studios' Movietone Follies of 1929. Most of the film takes place on the showboat of Mississippi entrepreneur Colonel Billy Batcher (Charles E. Evans). When the Colonel faces foreclosure after several failing seasons, soubrette Margie (Marjorie White) stages a fund-raising revue on the boat, enlisting the aid of all the big stars who got their start with Batcher. By an amazing coincidence, virtually all of the showboat alumni are under contract to Fox Studios! Janet Gaynor and Charles Farrell perform "We'll Build a Little World of Our Own," Victor McLaglen and Edmund Lowe kid their roughneck screen images in the novelty number "Vic and Eddie," Sharon Lynn and Ann Pennington offer the "hot" dance routine "Snake Hips," and "Whispering" Jack Smith offers a rendition of the title tune. Also on hand are Will Rogers, El Brendel, Walter Catlett (who also staged the musical numbers), Lew Brice (Fanny's brother), Dixie Lee (Mrs. Bing Crosby) and Georgie Jessel -- not to mention an uncredited 14-year-old chorus girl named Betty Grable.
