'What We Do in the Shadows' star Mark Proksch wants to see Bob Newhart make a cameo as an energy vampire

• "What We Do in the Shadows" star Mark Proksch told Insider he'd love to see Bob Newhart on the show.
• "It'd be my dream to get him on the show. I think he's an absolute genius," Proksch revealed.
• The actor said that he'd like Newhart to be an energy vampire, like Proksch's character Colin.

"What We Do in the Shadows" star Mark Proksch opened up about his dream guest stars on the FX vampire comedy, and one of them is legendary comedian Bob Newhart.

When asked by Insider who he'd most like to see make a cameo, Proksch joked that he's a fan of "all things old."

"A lot of the people I'd want to see on the show are dead," the actor said. "But Bob Newhart, who is thankfully still acting and still alive, it'd be my dream to get him on the show. I think he's an absolute genius."

Even though Proksch joked that some of stars on his wish list (which also included the late actors Max von Sydow and Don Knotts) were "nerdy," he didn't hold back in telling Insider exactly which role he'd like to see Newhart play on the show.

"I would love for him to have been the energy vampire that turned [my character] into an energy vampire," Proksch said of the famously deadpan 91-year-old comedian. "I think he would be an absolutely brilliant head of the energy vampires."

On the FX comedy, Proksch plays "energy vampire" Colin Robinson, a supernatural creature who feeds off his victims' mental stamina - mostly through engaging them in inane or boring conversations.

Past seasons of "What We Do in the Shadows" have seen numerous high-profile guest stars appear for an episode or two, including Beanie Feldstein, Kristen Schaal, Tilda Swinton, Evan Rachel Wood, Mark Hamill, and Taika Waititi, who wrote and directed the 2014 film that inspired the show.

"What We Do in the Shadows" stars Proksch, Matt Berry, Natasia Demetriou, Kayvan Novak, and Harvey Guillén. The first two episodes of the new season are currently streaming on Hulu, and new episodes are dropping every Thursday on FX. You can check out the trailer below.
