When talking to the High Lama, Conway sees the crutch next to the High Lama's chair and makes the connection between the High Lama and Father Perrault. However, when Conway first enters the High Lama's room, the long tracking shows the High Lama sitting in his chair, but there is no crutch next to it.

When Conway is stumbling down the mountain and approaching the native village, his hair and clothing don't match in closeup and distant shots.

The length of the pick handle held by Henry, when he stops to talk to Gloria about gold, changes between shots.

When Lovett and Henry debate directions, Lovett has the box in front of him, and in the next cut his coat and arms are on top of the box.

Father Perrault, a priest from Belgium, stumbled into Shangri La in 1734. Belgium did not exist then; it was established in 1830.

Though the inhabitants of Shangri-La are against violence and murder, they hired an assassin to kill Robert Conway's pilot and hijack his plane.

Even Eden had a snake. The ethos of a culture or population often does not apply to 100% of the inhabitants. Also, circumstances can sometimes force a person to act antithetically to their beliefs.

The plane comes to rest with the fuselage in the air, but it is half-buried when everyone gets out.

With the howling wind and the falling, drifting snow, it's quite possible that plane became partially buried in that timespan.

Robert and his brother George are evidently both Englishmen, but only Robert, played by the English-born Ronald Colman, has a British accent. Actor John Howard was American born and employs no English accent in his performance.

Accents are not innate. It's possible the brothers were raised apart or attended different schools; e.g., Robert at Eton and George at Harvard.

When Bob is entering Shangri-La, he is going down a mountain "upon which no man has ever set foot" but there are footprints in the snow in the foreground of the shot.

When Conway is chasing after Sondra on horseback, they are riding over grassy soil, but the sound of the horses' hooves is that of hitting a paved surface.

Camera shadow on Henry's back while on the plane, when he turns back to his seat.

Unless the inhabitants sent out for one (perhaps on the same order as the grand piano), there is a North American squirrel in a tree in Shangri-la.

Echoing the words of the critic, James Agate: 'The best film I've seen for ages, but will somebody please tell me how they got the grand piano along a footpath on which only one person can walk at a time with rope and pickaxe and with a sheer drop of three thousand feet or so?'

Experienced Sherpa mountain guides would know not to discharge a gun several times in snow-covered terrain because it might lead to an avalanche.
