The stand-up comedian is a special breed, both an artist and an artisan. They work by painstakingly developing a persona, scripting and editing an act, and revising it on the spot to suit the energy of a given audience. If the audience does not grasp the countless hours crafting the routine, and the empathic micro-calculations, then the act was a success... well, as long as it was funny.

Honing his craft as an indie filmmaker in Germany in the early 90s, Uwe Boll never could have imagined the life that lay before him. From working with Oscar-winning actors and making films with US$60million budgets to having actors publicly disparage him and online petitions demanding he stop making films, Boll continued to work; he has a filmography of 32 features, a career that has led to his new life as a successful high-end restauranteur. Already a cult legend, he will be remembered forever in the film world; for some, as a modern-day Ed Wood, who made films so bad, they're good, while for others, a prolific filmmaker who came from a small town in Germany and never compromised his integrity while forging his own unique Hollywood trajectory.
