Happy Days is a 1929 American pre-Code musical film directed by Benjamin Stoloff, which was the first feature film shown entirely in widescreen anywhere in the world, filmed using the Fox Grandeur 70 mm process. French director Abel Gance's Napoléon (1927) had a final widescreen segment in what Gance called Polyvision. Paramount released Old Ironsides (1927), with two sequences in a widescreen process called "Magnascope", while MGM released Trail of '98 (1928) in a widescreen process called "Fanthom Screen". The film features an array of stars who were contracted to William Fox's Fox Film Corporation at that time, including Marjorie White, Will Rogers, Charles Farrell, Janet Gaynor, George Jessel, El Brendel, Ann Pennington, Victor McLaglen, Dixie Lee, Edmund Lowe, and Frank Richardson. It also featured the first appearance of Betty Grable on film, aged 12, as a chorus girl, and Sir Harry Lauder's nephew, Harry Lauder II, a conductor for Fox, who was drafted into the chorus. Plot Originally titled New Orleans Frolic, the story centers around Margie (played by Marjorie White), a singer on a showboat who, when she hears that the showboat is in financial trouble, travels to New York City in an effort to persuade all the boat's former stars to perform in a show to rescue it. She is successful and the stars all fly to New Orleans to surprise the showboat's owner, Colonel Billy Blacher, with a grand show, the proceeds of which will go to rescue the showboat.
