Continuity mistake: During appetizers, John Leguizamo's assistant puts her work phone on the table to let him know she is resigning. Leguizamo is holding his glass when the camera is behind him, and a spoon when he's seen from the front. (00:13:10)
Continuity mistake: During the fourth course, after the gunshot happens, all the blood on the floor and kitchen bench disappears when the plates are about to be served. (00:42:12)
Suggested correction: This is simply because they very quickly and effectively clean the kitchen bench off-camera. That is why the man was standing on a sheet and they covered the open kitchen with a screen to catch the blood spatter. The blood on the counter was minimal and there was hardly any blood on the floor.
