Revealing mistake: Throughout the entire run of the series, special effects shots are repeated over and over, often half a dozen times in the same episode. Budget problems forced the practice, but at times it is so pronounced as to become a distraction. The same Cylon raider banking to the side, hit by laser fire and exploding outward to its sides, is probably seen more often than any other single shot in the show. It is flipped many times so that it can bank left, then be used to bank right, providing two shots for the price of one.
Revealing mistake: Several times, close up shots of the Cylon Centurions show the shoulders and chest moving slightly as the actor inside breathes. Though originally conceived as a reptiloid species, this never made it to screen. Centurions are robots who don't breathe.
