One of the most glaring visual errors in major motion-picture history was Alfred Hitchcock‘s decision to use this shot from North by Northwest (1959). A seated pre-pubescent kid (directly to the right of Eva Marie Saint‘s left shoulder blade), having obviously grown tried of listening to loud blam! blam! pistol shots over and over in rehearsals and/or previous takes, plugs his ears prior to Saint “shooting” Cary Grant.
