Some stars were already committed to other pilots, while others were brought in at the last minute when the roles were this close to being filled. And one friend almost played a different friend. Thankfully Cox, arguably the most well known of the sextet thanks to her work in Family Ties, Seinfeld and that one Bruce Springsteen video, had to foresight to ask to read for Monica.

"We were just blow away," Kanner admitted. "We were like, 'Oh s--t! I guess she's got to be Monica.'"
