In the opening shot of the Florida motel room, a boom microphone is visible in the window’s reflection between the curtains.
In the final cut, filmed inside the vehicle while en route to Cleveland, with the camera trained on Willie, the vehicle they are travelling in is no longer the 1965 Dodge Coronet but a Ford Econoline van.
When Willie and Eddie pause to ask a man in the street for directions, he tells them he's waiting for the bus — though there isn't a bus stop there.
Whilst Willie and Eddie stroll along the railway line in Philadelphia, the snow still bears the impressions of their footprints from an earlier take.
When Eva and Willy are in Willy's room watching television from their beds, the only light in the room comes from the set; instead of flickering, it casts a steady, even glow.
When Eva returns to the motel room to write Eddie and Willie a note announcing her departure, she places her hat on top of some clothes on the sofa bed by the window and then leaves. When the men come back from the races and find the note, the cash and the hat, there are no creased garments on the bed — only the hat remains.
While Eddie and Willie are driving to Cleveland, the camera and its operator are visible in the reflection of the rear-view mirror.
A crew member's shadow is cast moments before the scene concludes, as Eva throws the dress away.
When Eddie asks Willie whether they’ve reached Ohio yet, Willie replies that he reckons they’re still in Pennsylvania. However, above the motorway an overhead sign reads "Willoughby Hills", which is actually in Ohio.
When Willie and Eddie pause to ask for directions to Cleveland, a pair of men turn round and look at the actors and directly into the camera. Their reactions make them seem like ordinary passers-by who simply happened to be there, rather than cast members.
