He returned for “Twin Peaks: Fire Walk With Me,” “Twin Peaks: The Missing Pieces” and again for the Showtime reboot as Jean-Michel, although by then he was no longer able to stand.
His other appearances included a role as Nick the cable guy on the “Seinfeld” episode “The Cadillac” and a character named Bubba on Dolly Parton’s ABC variety show.
Olkewicz starred as Marko opposite Jeff Conaway on CBS’ “Wizards and Warriors” and appeared on NBC’s “Partners in Crime” in 1984, playing opposite Lynda Carter and Loni Anderson. He also portrayed Tiny McGee on “Who’s the Boss” and Walter Plimp on NBC’s “Night Court.”
He made his screen debut in “Futureworld” and went on to appear in films including Steven Spielberg’s “1941,” “The Big Picture,” “Stuart Saves His Family” and “Par 6.”
