Also, Laurie Holden (Marita Covarrubias) has pipes, and yes, that is Grey’s Anatomy’s James Pickens Jr. (Alvin Kersh) and The Princess Bride’s Cary Elwes (Brad Follmer) singing along, among many others. Love it!
Props to Michael McKean (Morris Fletcher) at the 2:50 mark for making me literally laugh out loud.
Duchovny even mentions the project’s parallels to a musical.
