Continuity mistake: When Homer is packing to leave for Oregon you hear the radio blaring in the background. His shirt is still unbuttoned, but then there is a cut to him watching himself in the mirror while he tries various basball caps, with his shirt buttoned and wearing a jacket. Ths wouldn't pass as a mistake if the radio didn't suggest continiuty. (00:00:50)
Continuity mistake: When Homer and Eddie have lunch on their first stop the pizza on the plate between them switches back and forth between untouched and half eaten. (00:15:15)
Continuity mistake: In the scene at the roadside bathroom Eddie is scared by the sound of a jet, thinking it's an earthquake. There's a very short cut to the aircraft, then back to Eddie, and all of a sudden she is not wearing her cap and hood anymore, for which there was neither a reason nor sufficient time. (00:20:15)
Continuity mistake: The blood stain on Eddie's bandage disappears in the roadside brothel and reappears in Summit Inn. (00:26:10 - 00:33:40)
Continuity mistake: When Eddie tells Homer about the Wady robbery while they're driving along, there's a change from broad daylight to late dusk in mid-sentence. (00:33:05)
Continuity mistake: When Homer drives off when they leave Summit Inn in the snow, he skids across the parking lot of the hotel, but a bit later it looks more like a frozen pond. As a pond could not be at level with the road and they didn't go down any slope this is a strange transformation. (00:40:10)
Continuity mistake: The establishing shot of the quay scene shows a close-up of a flock of seagulls. However, as the scene goes on we don't see any birds at all even when the camera shows the whole quay, but we hear them shriek. Only during the credits there is a skipped shot of the quay where it's crowded with seagulls. (00:57:20)
Continuity mistake: When Eddie sees the Jesus impersonator for the first time in a side road she asks Homer to back up. The stretch he reverses is much shorter that what they had covered since they passed the crossing. (01:10:20)
Continuity mistake: During the wake scene Homer's hair is combed flat. When he leaves the church it's standing up quite messily. (01:22:40)
Continuity mistake: At the German Hofbräuhaus party Homer talks to Eddie about getting back to work. In the background we see his old friend Betsy, who, after a short close-up on Homer, appears from the left to ask him for a dance, while there are totally different people in the background. (01:26:35)
Chosen answer: Just my opinion: Mae Mercer is a great jazz singer - and there is a soundtrack of this movie, just in case someone wants to check it out - and I am sure she was the one singing.
