And, as historian Daniel Gray opened the exhibition, he reminded people of its necessity in darker days.
He said: "When the cinema first opened it was dark times after the end of the First World War, and people would come into the light to forget about their problems and be taken to another place.
"The Pavilion is still doing that today. Escapism in front of the silver screen will never lose its appeal."
