15 Million Merits fun facts.
the episode was co-written by Konnie Huq a former presenter for the real-world UK talent spin-off The Xtra Factor.
It was purposefully aired immediately after a major X Factor finale.
The "Hot Shot" audition supposedly perfectly mirrored the look, feel, and judging dynamics of the actual previous talent show. (I'm not too sure about this last one. I think its a general statement).
Why you don't see it preformed on actual shows...The song is written by multiple people and then sung by a third so its notoriously hard to clear for use by production. Also apparently contestants seem to be apprehensive about singing it due to its association.
I think if it could get cleared for use...it would be a solid choice for a semifinal or even final round song.
