The "Smooth Criminal" segment is styled after a viral video of a cello duet version of the song performed by a Croatian duo called 2CELLOS (Luka Sulic and Stjepan Hauser). The duo also appears recreating their video with Santana and Sebastian.
The "Scream" segment is the second time where Kevin McHale who plays Artie is seen dancing while not in the wheelchair.
In this episode, Darren Criss who plays Blaine Anderson is seen as good guy while Grant Gustin's Sebastian Smythe is the bad guy. In Duet (2017) on The Flash (2014), the roles are reversed and Grant is the good guy where Darren is the bad guy.
This episode was originally scheduled to air on January 24th, 2012, however it it was pushed back to January 31st, 2012 due to the State of the Union address.
