After the Final Curtain
"People buy tickets to theatres, not movies." — Marcus Loew
After the Final Curtain 
Are there any pictures of the interior during the Cinerama era? I saw “It’s a Mad, Mad, Mad, Mad World” there in 1963.
Not on here. This site is mostly photographs that I have taken of these theaters. You can find some historic photos at the Friends of the Boyd.
