Stacker is embracing imperfections by listing mistakes from the 50 best movies of all time. Rankings are based on a score Stacker derived from equally weighted IMDb ratings and Metacritic scores.

Hollywood movie-making takes time, money, cooperation, careful planning, and a painstaking knack for detail. But even the most meticulous preparations sometimes can't spare a film from its share of goofs and mistakes to the delight (or chagrin) of observant viewers.

The majority of these goofs take the form of simple continuity errors. For example, a glass might be full in one shot and empty in the very next. Other mistakes appear by way of historical misfires, major plot holes, visible camera equipment, or crew members getting caught in a shot. And every now and then, the annals of cinema are graced with a goof of epic proportions. For example, white cars can be seen in the background during a battle scene in “Braveheart.”

The much-publicized Starbucks cup in “Game of Thrones” was hardly the most notable example in entertainment, though it shows a simple point: Even with the advent of CGI and advanced editing technology—not to mention fully financed production crews—human error is often unavoidable. You probably could have guessed that Alfred Hitchcock, one of the most legendary filmmakers, appears more than once on this list; but even the “Master of Suspense” fell victim to, well, obvious visual and plot points.

When critically acclaimed films from Francis Ford Coppola (“The Godfather”) or Martin Scorcese (“The Irishman”) exceed three hours in runtime, should we be more forgiving?
