Bringing in Matchbox Twenty’s Rob Thomas to sing the jingle for iZombie’s in-series drink Super Max began as a writers’ joke—he shares a name with the CW drama’s executive producer, Rob Thomas, and the two are often mistaken for each other.
But the gag felt right, so Thomas reached out to his namesake via Twitter’s private messaging, and asked if he’d sing the song and then appear in the Season 2 finale. The crooner (above, second from left, in a behind-the-scenes shot with Robert Buckley, Rose McIver and Malcolm Goodwin)—who is a fan of the series—agreed, and plays himself at a prison-themed Super Max party in the April 12 season finale.
Of course, things take a turn at the Max Rager party. “You don’t want everyone locked up when there are zombies around,” iZombie’s Thomas teases.
