When the Goodies are setting off on their holiday, Bill falls off the bike. He gathers up all the luggage that he dropped, but not his large hat, which had also fallen off. In the next scene, where he is shown chasing Tim and Graeme to Penrudden Cove on foot, he is wearing his hat.
In the comedy advert for the Westminster sub-machine gun, it is obvious the lady is not pointing the gun at Tim. Also in the close up, she is holding the barrel of the gun which would burn her hand, if it was real.
