It is a little bit disturbing when you look at these full-grown adults playing teenagers and then compare that to wha a teenager would actually look like. In many cases it's baffling to me when they cast as old as they do. For Smallville they cast mid 20's Tom Welling to play Clark Kent and then gave him lots of sexy moments to appeal to the audience, but he was techniqually supposed to be 14/15 when the series began and they were giving him those shirt-ripping scenes...
