The failure of Brett Ratner's $75 million Tower Heist last weekend was overshadowed by the director's bigger failures as a human. Still, it must be asked: What went wrong? Heist had plenty going for it, including a timely premise, a release date light on competition, the usually bankable Ben Stiller, Eddie Murphy in his most promising role in years, and some of the least-awful reviews of Ratner's career. Predicted to top the box office with at least $35 million, Heist made off with a mere $24 million, landing in second place behind the week-old Puss in Boots. So as Ratner embarks on an apology tour, Murphy sulks back to movie jail, and Stiller calls his agent to see if there are any Fockers we haven't yet been introduced to, we asked a pair of Hollywood professionals (a prominent agent and producer) for insight into why Tower Heist bombed — and what the fallout might be for its makers.
