On Twitter, Aimee Garcia (Ella Lopez) revealed Tom Ellis (Lucifer) was able to perform the dance sequence after just one rehearsal.
Tom Ellis suggested the bit where Lucifer tosses Kevin Alejandro (Dan) into the rafters during the dance sequence.
At a fan event, Tom Ellis revealed they filmed a sort of postscript to the dance sequence where Dan crashes to the floor after Lucifer leaves the station.
A special sleeveless dress shirt was custom-made for Tom Ellis (Lucifer) to wear under his suit during the dance sequence, because the tailored, sleeved ones were too tight to allow him to easily and safely raise his arms in them. Behind-the-scenes video showed he technically could raise his arms, but not without the cuff links becoming flying projectiles.
As of this episode, this is the highest rated season of the whole series.
