Man on a Ledge

Man on a Ledge is a caper movie we watched because it looked vaguely intriguing in the trailer on another DVD. Ex-cop, convicted of stealing an improbably huge diamond from a real estate developer, escapes from prison and climbs out on the ledge of a hotel owned by the developer, pretending to be ready to commit suicide. It's all a ploy to cover-up actually stealing the diamond, which the developer hid and claimed the insurance on to cover losses in his deals. Aside from the numerous suspension of disbelief problems --- the cop is accused of cutting up the diamond and selling off the pieces? how?  and how many crimes did he, his brother, and her girlfriend commit in actually getting the diamond in their hands to prove his innocence? --- this is really nothing that's never been done before and better.
