"Smash-Up: The Story of a Woman"

We get a short montage as a marginal singing cowboy played by Lee Bowman rises to become a major singing radio star in "Smash Up: The Story of a Woman" (Universal-International, 1947). This shot features an unidentified theatre. 

At the beginning of the film we see that his wife, played by Susan Hayward, was headed for quite a singing career herself. But after her marriage as the husband's career blossomed she felt neglected and started serious drinking. Also featured are Marsha Hunt, Eddie Albert, Carl Esmond and Carleton G. Young. It was written by John Howard Lawson, Lionel Wiggam and Dorothy Parker. Stewart Heisler directed. The cinematography was by Stanley Cortez. 

The second image we get is of the Four Star, on the Miracle Mile at 5112 Wilshire Blvd. See the page about the Four Star Theatre on the Los Angeles Theatres site. 

The last marquee we see in the montage is a doctored view of the Beverly on Beverly Dr. in Beverly Hills. The marquee actually had the theatre's name above the three readerboards. See the Los Angeles Theatres page about the Beverly Theatre for photos and more information.
