pompously tries to get Mainwaring to leave the situation in the hands of the regular army, but is quick to cancel an incautious order for mortar bombs under Mainwaring's persuasion. Walker returns and tells Mainwaring that he's talked to the man in charge of the reservoir: he has opened the sluices, and the Germans will have to swim for it in less than two hours. Laughing, Mainwaring says they should leave the mopping up to the Coldstream Guards. Cast Arthur Lowe as Captain Mainwaring John Le Mesurier as Sergeant Wilson Clive Dunn as Lance Corporal Jones John Laurie as Private Frazer James Beck as Private Walker Arnold Ridley as Private Godfrey Ian Lavender as Private Pike Janet Davies as Mrs Pike Bill Pertwee as ARP Warden Hodges Avril Angers as the Telephone Operator Timothy Carlton as Lieutenant Hope-Bruce Stanley McGeagh as Sergeant Waller Pamela Cundell, Olive Mercer and Bernadette Milnes as the Ladies in the Queue Gilda Perry as Doreen Linda James as Betty Richard Jacques as Mr Cheesewright Colin Daniel and Carson Green as Boys Notes The working title for this episode was 'Sorry, Wrong Number', which was the title used for the later radio episode. The episode title is a reference to the 1939 propaganda film The Lion Has Wings. When Jones accidentally rings up the cinema, they mistakenly believe he is enquiring about the 1942 film One of Our Aircraft Is Missing starring, as they tell him, Googie Withers. A poster for this film can be seen on the wall of the box office. In this episode, Sgt Wilson says "I have never heard you swear before, sir", when Captain Mainwaring says "bloody cheek". This is untrue, as Wilson has heard Mainwaring say "the rotten bastard" in The Showing Up of Corporal Jones, an episode from Series 1. When the ladies join the queue for the telephone box, Pamela Cundell's character is referred to as Mrs Fox, the character she played two episodes previously, yet she is still credited as 'Lady in Queue'. In 2020, for the Dad's Army Appreciation Society, Niles Schilder wrote four scripts about how the platoon would have dealt with the events of 2020. In one of the scripts, An Unauthorised Gathering, the platoon learn how to wash their hands in a similar way to how they learnt to use a public telephone box in this episode.
