The scene where Jo says goodbye to Jimmy for the last time is shot at Barton Swing Bridge, on the Manchester Ship Canal. Jimmy walks through the closing barriers to the end of the bridge and is next seen on the ship, but there isn't a way for Jimmy to get off the bridge and onto the ship as the far end of the bridge hangs over the canal. Jimmy would have had to fall 15 feet whilst leaping around 20-30 feet to make it to the deck of the ship. Quite an achievement in those boots.
During the opening credits bus ride through Manchester the very large building on Portland street overlooking Piccadilly Gardens (now a Thistle hotel) has large letters across the top on each wing identifying it as "Hickson, Lloyd & King Ltd.", but in the shot, the letters are all backwards in a mirror image.
