2. The black and white film which has the crucifix at the top of the staircase?

What is the name of the black and white film which has the crucifix at the top of the staircase? It's from the late 1950's or very early 1960's. I've never forgotten that scene since I first saw it as a small boy in a theater with my parents in the very early 1960's. I've never seen that movie again since I watched it in that theater. There's a scene in The Blues Brothers movie where the director, Landis, similarly depicts a crucifix at the top of the staircase when Joliet Jake and Elwood go and visit the Nun prior to their "mission."
