Movies and weddings are — it must be said — a match made in heaven. Nell Minow, The Movie Mom, selects 50 of the best movies about proposals, engagements, and weddings from classics (“Father of the Bride,” “The Godfather”) to neglected gems like “Confetti” and “The Baxter.” Comedies, romances, dramas, runaway brides and wedding crashers — these are must-see for anyone who has ever planned, dreamed of, or been to a wedding.
