The character Bill (played by Winston Story) really does have an uncanny resemblance to Charles Boyle (played by Joe Lo Truglio). I know that the Brooklyn Nine-Nine production do sometimes work off-set truths into the show (such as Terry Crews' real love of yogurt or Stephanie Beatriz's bisexuality), and I wondered if Winston served as a stunt double for Joe and they decided to incorporate the resemblance into episodes for humorous effect.
Was Winston involved with the show before he was cast as Boyle's lookalike, Bill, or is the likeness more of a coincidence?
