* SelfAdaptation: It started as the ''Three Blind Mice'' radio play written by Creator/AgatheChristie that she adapted into the short story of the same name and then turned into the titular play.

Even then, the show returned the following year, so no, COVID-19 is not going to provide whoever currently owns the film adaptation rights an excuse to start making one right away.
