In addition to Matthew McConaughey voicing the King, “Agent Elvis” has a ridiculously stacked cast of voiceover performers. Don Cheadle plays The Commander, the leader of The Central Bureau (“TCB”) agency, who oversees all of the spy missions and is responsible for bringing Elvis on board. Kaitlin Olson plays CeCe Ryder, another secret agent who lives to bring the King grief. During his missions, Elvis has allies in the form of his less-than-intelligent sidekick Bobby Ray (Johnny Knoxville), and Scatter (Tom Kenny), a former NASA chimpanzee with a bit of bloodlust. And of course, pop music’s most memorable mama’s boy has to have a maternal figure, who in this show appears as Bertie (Niecy Nash-Betts), described as “one of the few people who can challenge the King.”

“Agent Elvis” also boasts an all-star cast of guest appearances, including Jason Mantzoukas, Ed Helms, Christina Hendricks, Chris Elliot, Fred Armisen, Kieran Culkin, Simon Pegg, Ego Nwodim, Asif Ali, Craig Robinson, George Clinton, Gary Cole, Tony Cavalero, voiceover legend Tara Strong, and Elvis’ real-life ex-wife, Priscilla Presley.
