Lady Ruff-Diamond is seen to become covered in plaster like everyone else during the dinner party. For the last two shots of her speaking at the table and in the subsequent scene outside the residence, however, she is the only one spotlessly clean once more.

During the bombardment of the British Consulate, there is a self-repairing window and blind situated behind the piano.

When the real chiefs arrive, Bungdit Din walks in the room to see the fake chiefs in the fountain with the girls. Brother Belcher ducks underneath the water, then it cuts to a side view and you can still see Brother Belcher above water, then it cuts back to the front and you see Brother Belcher surface.

When everybody sits down to dinner during the battle at the end, a part of the ceiling collapses and the dust falls on Sid's right shoulder. The dust mark changes size throughout the dinner scene.

During the palace dance scene, Busti is seen watching the dance alongside Bungdit Din. Moments later after the dancers flee outside into the palace yard, Busti is seen again with the Fakir.

When Bungdit Din and the Khasi launch their attack against the British they fire cannons at either side of the gate. However, when the damage is sustained to the wall, the bricks fall towards Bungdit Din and Khasi against the direction of fire when they should have fallen away from them in the direction of fire.

The film is set in 1895. When dictating a letter to Queen Victoria, Sir Sidney Ruff-Diamond adds "PS, Love to Albert". Prince Albert, Victoria's husband, died in 1861, 34 years before the film's events supposedly take place.

During the polo match Sir Sidney mentions Philip, clearly implying the future Prince Philip, ignoring the fact that The Duke of Edinburgh was not born until the 1920s.

Pte. James Widdle (Charles Hawtrey) is wearing NHS (National Health Service) issue spectacles which were not introduced until 1948.

After Captain Keene asks if he can "have a bash", a man in a turban approaches Sidney. Sid's lips are moving and say, "Do you wish," but there is no sound. Then in the next shot we hear him say, "Do you wish to see me?"

Captain Keene informs Sidney Ruff-Diamond that Princess Jelhi told him that her father has a photograph of the inspection parade (showing the soldiers were wearing underpants). However in the previous scene, Princess Jelhi makes no mention of the photograph, only that her father was planning an uprising to kill all the British.

During the Dinner scene, Angela Douglas repeatedly smiles at Peter Butterworth as he reacts to the chaos around him. She admits in a later interview that many of her close up shots are edited out of the final cut as she couldn't keep a straight face.
