Variety Lights (1950)

When a beautiful, talented young woman joins a provincial vaudeville troupe, suddenly they're playing to packed houses and their aging comic Checco Dalmonte gets big ideas. Checco falls in love with the ingenue, Liliana, and ignores Melina Amour, his long-time companion who wants to marry him and is saving up to open a deli. Also, believing he can be an impresario, he hires other actors and begins rehearsal for a revue that will star Liliana and himself. Liliana admires Checco, but she's being squired around town by Adelmo Conti, the assistant to the region's biggest impresario. Can Checco's new troupe hold onto Liliana, and can Melina hold onto Checco?
