Blooper

In Heinrich Stubel's bedroom, not too far from the end of the film, a lounge chair is visible by the closet, yet the next shot of the closet - the chair is nowhere to be seen.

In the police station near the beginning of the film where the murder of the manager has been reported, there is a fan spinning above the officers' heads. Yet toward the end of the film during the escape scene, the fan has disappeared.

When Chico is playing the piano with the orchestra, he gestures with his baton twice before throwing it at the musicians. However the trumpeter on the left anticipates him throwing the baton and can be seen flinching on the first two gestures.

When the building that Rusty is leaning against collapses, several of the black guide wires are visible.

When the police prefect gives the order to "Round up all likely suspects," his lips clearly say, "Round up the usual suspects" (see trivia).

When Rusty finds the treasure room, just before he moves toward the harp, the light shadow of a film crew member can be seen briefly.
