For the episode Beacon, TheCW hosted the "Believe in Heroes" Challenge  from Friday, December 10, 2010 through Monday, December 20, 2010 to allow fans an opportunity to appear in the episode. In these videos, viewers - speaking in character as impassioned citizens of Metropolis and around the world, fighting for the rights of their heroes - could express what The Blur means to them and talk about why they believe in these super heroes.
According to the press release, the context of the show will have "Clark's friends assure him that he is, indeed, making a difference in his crime-fighting role as The Blur, and to prove their point, they show him videos from the Internet in which ordinary citizens express what The Blur means to them, what it means to be a hero - and what it means to have heroes and believe in them. One of these videos could be yours!"
The producers and the CWTV.com team will review the submissions and select a number of the user-submitted videos for broadcast as the testimonials that Clark watches during Beacon.
In addition to selecting the winning videos to be used in the episode, the "Smallville" producers and CWTV.com team will also select a number of additional favorite videos that will be posted to CWTV.com following the broadcast.
The winners have not yet been announced.
