Fred Armisen will be ringin’ (and singin’) in the holiday season.

The 47-year-old half-Venezuelan actor and former Saturday Night Live star has been added to the voice cast of NBC’s animated holiday special Elf: Buddy’s Musical Christmas.

Toplined by The Big Bang Theory star Jim Parsons, the animated special is set to air on December 16 at 8:00 pm ET. Parsons will voice Buddy in the special based on the 2003 film Elf starring Will Ferrell and the hit Broadway show Elf: The Musical.

Santa narrates the story of Buddy’s travels to New York City to meet the father he never knew he had. Along the way his unrelenting cheer transforms the lives of everyone he meets and opens his father’s eyes to the magic of Christmas.

In addition to Armisen and Parsons, the Voice cast also includes Mark Hamill, Ed Asner, Jay Leno, Matt Lauer, Gilbert Gottfried, Kate Micucci, Rachael MacFarlane, Max Charles and Steve Higgins.
