The look of the Pantages at the 1954 "A Star Is Born" premiere got re-created for Anton Corbijn's film "Life" (Cinedigm, 2015). The film is about Life magazine photographer Dennis Stock, played by Robert Pattinson. He's supposedly after some photos of James Dean. Thanks to the website Films in Films for the screenshot.
The Pantages shoot in progress. Thanks to the blog Twilight Girl for the photo. See their page for more views.
Another "Life" shoot image. It's another one from the Twilight Girl blog.
Head to the sections about the Pantages Theatre on the LA Theatres website for history and many, many photos.
On IMDb: "Life"
