Tonight starting at 8:00pm, the Discovery Channel will look fifty years into the future with a three-part series called 2057. The series will mix speculation from leading scientists with dramatic storytelling to try and envision how our world will change over the next few decades. One of the questions, of course, is whether or not we'll have flying cars, and more importantly, will Martian hookers be both plentiful and affordable? Okay, the second one is my own personal preference, but I think it's worth looking into.

The first part of the series, "The Body" airs at 8:00pm and looks at modern technology and what it holds for human health and longevity in the future: things like robotic surgery and custom-built organs. At 9:00pm, "The City," the second part in the series, will look at advances in robotics, automobiles and surveillance systems. Finally, at 10:00pm, "The World" will examine how technology will help transfer more information even faster than before, and the possibilities of space travel for average folks like us.

Extras (Sun., 10PM, HBO)
Harry Potter is a dirty, dirty boy. Daniel Radcliffe guest stars on 'Extras,' where he hopes to shed his innocent image by making a very indecent proposal to Maggie. Dumbledore would be aghast. Meanwhile, Andy (Ricky Gervais) is a laughingstock after he makes a faux pas at a restaurant.
