Today - Thursday, September 10th, we're celebrating the 51st birthday of Chris Columbus, the film-maker who directed the first two Harry Potter movies, Philosopher's Stone and Chamber of Secrets! He also produced Prisoner of Azkaban. Even though Chris hasn't made a return to Potter, he's directed some big films during his career, including Home Alone and Mrs. Doubtfire, and he's also produced films such as Fantastic Four, Night at the Museum and Rent.

Happy Birthday, Chris!
