"Too Much Harmony"

We spend lots of time in the Belasco Theatre, 1050 S. Hill St., in the 1933 Paramount musical "Too Much Harmony." About 25 minutes into the film when we get to New York the Belasco is standing in for Merlin's Theatre. Here we're looking offstage left during a rehearsal. We also get some murky views to the rear of the auditorium.

When Merlin isn't happy with the singing of his leading lady he says "I wish you were Helen Morgan," referring to one of Ziegfeld's big stars. She retorts: "I wish you were Earl Carroll." 

Harry Green plays the theatre owner, Bing Crosby is the star of the show, Kitty Kelly is the female lead, Jack Oakie and Richard "Skeets" Gallagher are two vaudevillians Bing meets while checking out a small town show and Judith Allen is Oakie's girlfriend that later falls for Bing.

Theatre owner Harry Green is sitting onstage with some of the Belasco's distinctive proscenium plasterwork on the left.

Allen, Gallager, Kelly and Oakie plotting to get Bing's evil girlfriend to break off the engagement so he'll be free to marry Allen. Earlier the fiance had threatened to make Bing's life hell if he didn't go through with the marriage. Oakie is going to pretend he's a southern tobacco plantation owner.

Kelly and Oakie off right preparing to go on for the finale, most of which was shot on a Paramount soundstage. The dimmerboard is to the left of Ms. Kelly.

The Belasco opened in 1926. Designed by Morgan, Walls & Clement, it was initially a legit house featuring plays, as opposed to its next door neighbor, the Mayan, that did mostly musicals. The theatre still survives, although turned into a music and events venue. See the pages about the Belasco Theatre on the Los Angeles Theatres site for a full tour.
