Continuity: Indians are on a hilltop and a jet vapour trail can be seen in the sky.
Continuity: In the scene at The Yellow River where the Indians are chasing Gregory Peck and the gang of Omar Sharif on their way to the draft, you can see the same sequence with some trees (filmed with the camera holding up) twice within a second.
Continuity: In the final scene, after escaping the earthquake, you can see Camilla Sparv jumping across a gap with her horse shortly followed by Gregory Peck. You can see the clouds changing very fast within a split second.
