The RiffTrax gang will be back in theaters this December, thanks to Fathom Events. Mike Nelson, Bill Corbett, and Kevin Murphy will be putting poor Dropo through the wringer once again as they rebroadcast their 2013 riff on the Mystery Science Theater 3000 favorite Santa Claus Conquers The Martians. In an A.V. Club exclusive podcast, the trio reminisce about Nicholas Webster’s 1964 sci-fi comedy—one of the lamest Santa Claus movies not featuring Dudley Moore—and discuss working with “Weird” Al Yankovic and getting into the Christmas spirit in the chilly climate of San Diego.
