Bell
From Battlestar Wiki, the free, open content Battlestar Galactica encyclopedia and episode guide
Bell is a curly-haired cameraman, working alongside D'anna Biers for her documentary on Galactica (Final Cut).
Because of his devious behavior and close working relationship with Biers, whom viewers (although not Colonial characters at the time) know to be a Cylon agent, some viewers suspect he is also a Cylon.
Note
"Flick" Harrison, who plays D'anna's cameraman, is really a filmmaker, journalist, and cameraman. He wrote about the experience on his blog.
