Ever been watching your favourite TV show and noticed a glaring inconsistency or a problem with the set? Or even that a character's lines are being said without them even opening their mouth? In the episode 'Three Men, a Woman, and a Baby' in Only Fools and Horses, they are in the hospital at about 2 a.m. but reflections and the view out of the window show broad daylight. When all the Friends are at Ross's place in 'The One With All the Poker', Marcel is dancing to the music; there is a reflection in the TV screen of the animal trainer directing the monkey. Following on from the successful books on Movie Mistakes, Jon Sandys has turned his attention from the big to the small screen, covering shows from the UK, the USA and Australia in a highly entertaining guide you won't want to miss.
