Moonwalker (1988)

Revealing mistake: When Michael and Spike are having a dance off, behind them the road continues. It is so obvious that the road is just a backdrop, along the road the texture and colours change at one particular point, also the sky.

Michael: Do it and you're dead.
Mr. Big: Let's give her a shot of this.
