1. Joel Schumacher
Joel Schumacher is, to me, a fascinating filmmaker, having worked in just about every film genre going, and having crafted a series of works that range in quality so drastically. He's clearly not the most talented director out there, but when he gets some strong material, he totally knows what to do with it, and has crafted countless iconic and memorable films throughout his career. He's also directed his share of dreck, and that might go a way to explain why two of his latest films, Blood Creek and Twelve, didn't even get a proper theatrical release, subsisting largely on the home video circuit. Unlike most of the directors on here, Schumacher started out with a few flops (The Incredible Shrinking Woman, DC Cab, St. Elmo's Fire), before finding his footing with the inimitable classic The Lost Boys. After Flatliners and Dying Young were both given mixed responses, Schumacher hit his stride, delivering the blackly comic masterpiece Falling Down, the stellar legal drama The Client, the underrated style-over-substance exercise Batman Forever, and the classic race drama A Time To Kill. His next film, however, left him out for the count; Batman and Robin is regarded by many as one of the worst films ever made, and was a financial disappointment to boot. It's at this point in his career that the duds started to overwhelm the good films; efforts like Tigerland and Phone Booth became outnumbered by Bad Company, The Number 23, and the Nicolas Cage flop Trespass. Most recently, he has returned to the world of TV to direct two episodes of the acclaimed Kevin Spacey drama House of Cards. What this makes clear is that the guy needs someone to select his scripts for him, because he's clearly talented, but just exercises terrible judgement. Who do you think are the most inconsistent filmmakers in film history? Let us know in the comments below.
