It's a very Shane Black Christmas here at JoBlo – with us taking a look back and his underrated whodunit – KISS KISS BANG BANG – a private eye thriller that revitalized the career of leading man Robert Downey Jr. So acclaimed was his performance that it arguably landed him IRON MAN, even if the film itself underperformed at the box office. It's a real gem, with great performances by Downey Jr, Val Kilmer and Michelle Monaghan.
