Series scriptwriter Dennis Spooner said that the series would frequently feature Steed visiting busy public places such as the main airport in London without anyone else present in the scene: "'Can't you afford extras?', they'd ask. Well, it wasn't like that. It's just that Steed had to be alone to be accepted. Put him in a crowd and he sticks out like a sore thumb! Let's face it, with normal people he's "weird". The trick to making him acceptable is never to show him in a normal world, just fighting villains who are odder than he is!"
