The Real World 20 is having problem finding people suitable for the premise that seven twentysomethings actually have goals. According to Reality Blurred, MTV casting directors are having trouble finding people who match the show's description of people wanting to actually do something with their lives. They're just getting the normal people who are aspiring actors trying to break into the business.
The article also elaborates on how casting will most likely be extended in the near future, since they don't want to be overwhelmed with tapes all at once.
And it also responds to "rumors" about casting tapes being uploaded to MTV.com and people at home actually being able to select a finalist. Apparently, Damon Furburg, the casting director that Reality Blurred talked to, has heard nothing about it.
