Revealing mistake: In a recent episode (April 08), Lloyd referred to Steve as Simon during a conversation in the Rovers. Simon happens to be Steve's real name. Oops.
Revealing mistake: In the 5th November episode when Sophie takes Audrey's fur hat off Beth and throws it in the fire, there are flames licking the hat, yet the hat itself doesn't catch fire, because when Keith retrieves it, it is unburnt. So the hat must either be made of asbestos or the flames are computer generated, not real.
Revealing mistake: In the 11/04/07 episode when Jason is hugging his baby and talking to his mum, it is extremely obvious that in some shots the baby is a rigid plastic dummy.
Revealing mistake: In a recent episode, Roger is shown carrying a box with a 42" plasma TV into Janice's flat. Plasma TVs are very heavy, so it's most likely the box that Roger was carrying was empty.
