Continuity: Jim Dale and Anita Harris think that Barbara Windsor is going to jump off the roof and race across the road into the nurse's block.

Continuity: When Mr Roper is asking the nurse if he can have a fag, he is told to take his medicine, so he takes it. But in the next shot, when the nurse has gone and he is holding a newspaper, the medicine has disappeared.

Continuity: As dawn breaks on Frankie Howard's first morning in the hospital, the tea orderly leaves his trolley with two cups of tea and starts walking towards Sid James' bedside cabinet. However when he deposits Sid's cup of tea he is clearly only carrying one cup.
