Hudson Hawk (1991)

Revealing mistake: Gratuitous car explosions are nothing new in action films ... but this time the ambulance explodes in mid-air before even hitting anything. (00:32:22)

Trivia: The film was a passion project for Bruce Willis for nearly a decade before production. It was based on a character and concept he came up with, with the help of songwriter Robert Kraft. The concept was originally written to be the basis of a semi-comedic song, but Willis and Kraft loved the character so much, they decided to try and adapt it into a feature film. Willis' success with the "Die Hard" franchise gave him the power to get the film made. However, the passion project quickly turned into a nightmare, with creative clashes between Willis and director Michael Lehmann, extensive re-writes being done on-set, and a generally troubled shoot. It ended up being the only film project Bruce Willis received a writing credit for.
