Continuity mistake: When the men go up to Stallone's hotel room, you can see them going down a long passage and passing a few rooms before coming to his door. But when the room blows up, the shot from outside the building shows nothing to the left or right of his room. What happened to the rest of the floor?

Continuity mistake: In the love scene with Sharon and Sly, they stand beside the bed and Sharon puts her purse on the bed, when the camera changes shots and returns to the angle the purse is on the floor.
