The Mayan Theatre makes its first of many movie appearances in "It Couldn't Have Happened (But It Did)" (Invincible Pictures Corp. / states rights, 1936). The comedy romance features Reginald Denny as a playwright who is accused of murdering the two producers who were putting on his play.
See our pages on the Mayan Theatre for many photos of the 1927 legit house, a design of Morgan, Walls & Clements. The theatre, at 1038 S. Hill St., is now thriving as a music club.
