"Let's Do It Again"

The Tower, Rialto and Orpheum appear briefly in Sidney Poitier's "Let's Do It Again" (Warner Bros./First Artists, 1975) although we're supposedly cruising around New Orleans.

See the Los Angeles Theatres site's pages on the Tower Theatre for a history of the 1927 vintage film palace along with hundreds of photos. The pages on the Rialto Theatre down the block detail its life from a 1917 film house to its current incarnation as an Urban Outfitters store. The various pages about the Orpheum Theatre have many photos of different areas of that great 1926 vintage vaudeville house. 

That hulk on the right with the dim blue neon is the Optic Theatre, 533 S. Main St. On the left is the Santa Fe Building vertical sign at 6th & Main. See the Los Angeles Theatres page about the Optic Theatre for a history of the building and many photos. It opened in 1911 and lasted into the 1980s.
