Continuity mistake: The spacing (almost touching versus several inches apart) and appearance (shape and whether there are shoots) of the two flowers in the vase on Estelle's/Betty's table at the restaurant vary. Sometimes, the flowers on her table look more like the ones that could be seen on the table in front of hers after Brian/Roy entered the restaurant. (00:03:40)
Revealing mistake: There is a large "Inglorious Basterds" poster on the wall of the building (to the left of the screen) when Roy and Betty stop at the bench along the sidewalk. The poster should still be visible when they resume walking, but there is a window in its place. (00:10:57)
