We get a look at the Highland Theatre in Highland Park in "Lights Out" (New Line/Warner Bros., 2016). It's a story about a supernatural being that threatens a family when (are you ready?) the lights go out. The film, directed by David F. Sandberg, stars Teresa Palmer and Gabriel Bateman. Thanks to Jonathan Raines for spotting this one and sending the information our way.
The theatre, at 5604 N. Figueroa St., is a 1925 design by L.A. Smith for West Coast Theatres. Now a triplex on the main floor, its unused balcony still has most of the original decor. See the Highland Theatre page on the Los Angeles Theatres site for a photo tour.
