There was brief homage to Neil Peart in last night's Season 5.5 premiere of Showtime's Billions (Season 5, Episode 9 - Implosion). Wendy Rhoads (Played by Maggie Siff) was talking to her boyfriend painter Nico Tanner (played by Frank Grillo) about his rise to popularity and says, "Penthouse walls, echo with the sound of salesmen." To which Nico replies, "That guy was an artist. Right? Neil Peart?". The reference comes in around the 9-minute mark (thanks RUSHnATL and Kelly P). You can watch it below or on YouTube. Billions Showrunner Brian Koppelman is a huge Rush fan and purposely inserted the reference, as he warned in this tweet yesterday:

Today is Neil Peart's birthday. Artistic giant. Legend. Gone way too soon. For Peart fans, there's a little something for you in tonight's ep of #Billions. It's already avail on demand and on showtime anytime. As NP said: You can choose.

This is not the first time the show has included a Rush reference. Back in Season 4 (Season 4, Episode 9 - American Champion) Rush's 2112 Overture was played during one scene. At about the 25:30 mark in the show, Bryan (Toby Leonard Moore) is at a cycling exercise class where Rush's 2112 Overture is played for about 40 seconds. Also in Season 4 (Episode 2 - Arousal Template) Taylor punches in a 4-digit access code into a keypad to open a door, and the code is - of course - 2-1-1-2 as seen in this tweet. In episode 9 of season 3, Axe and Taylor spend a portion of one scene debating which is Rush's best album as seen in this post.
