Attending a double bill these days is an act of devotion, a genuflection before an eye-patched auteur or blood-spattered genre. These two-barreled day-wasters are now the preserve of repertory houses, but at one time they were everywhere, when the weekly dose of B-movie pulp, newsreel, and high-toned prestige pic was the studio-mandated regulation.

Now it’s one and done since the double feature went the way of the drive-in. Today, a double is the domain of the movie-lover, the nerd, the completist. (We’re talking theater-mandated twofers only, of course, as multiplex screen-jumping presents its own à la carte thrills.) But when all the preliminaries have been decided, the sight lines approved, and the nearest patrons smell-checked, the question looms: what do we do during intermission?
