This episode has Toast see Kubrick fake the moon landings. However rumours linking Kubrick with the faking seem to go back to at least 2012.
Possibly this was based on some acting pitch to say that an actor was available to work in London? As opposed to a provincial actor, for instance?
It is a pun on Toast coming from London (like Laurence of Arabia) and the phrase meaning someone (often an actor in the west End) is acclaimed for their success ( He was the toast of London) coming from the habit of raising a glass in a toast actors.
