Continuity: At the Zurich sanction when Jonathan kicks the killer out of the window, just before he kicks him, look at the window. This window has two panes of glass that open outward, with the latch in the middle, but a view from the outside shows that it's a single window with one pane of glass in it, not big enough for two panes.
Continuity: At the beginning, the guy who is Jonathan's friend is in his hotel room, and when he hears a noise it cuts to the bad guy in his place. There is a brown bag hanging on the wall, but in all following shots the bag isn't there. It can't be on the floor because at the start of the fight they go to that wall where the bag was, so they should have knocked it off.
Continuity: In the scene at the end, after the bad guy has fallen off the mountain, Clint Eastwood is hanging in front of the tunnel window. He slowly removes and drops his gloves, so that he can take out his pocketknife and cut the rope. He then cuts the rope, but when he is hauled in by his rescuers he is wearing his gloves.
