Career
Stage
Harris submitted a fabricated resume to the Millpond Playhouse on Long Island in 1939 and was hired by director Richard Brooks, who cast him in 26 productions during the summer of 1940.1 He reached Broadway in 1942 with The Heart of a City, in which he played a Polish officer,1 and in 1946 he starred opposite Marlon Brando and Quentin Reynolds in A Flag Is Born.1
Early television (1949-1962)
Harris made his television debut in 1949 on The Chevrolet Tele-Theatre and over the following decade became a fixture of live anthology drama, appearing in Studio One, Hallmark Hall of Fame, Goodyear Television Playhouse, Armstrong Circle Theatre, Climax!, Schlitz Playhouse of Stars, and many others.1 He appeared in the 1953 feature film Botany Bay.
From 1959 to 1965 he co-starred with Michael Rennie in The Third Man television series, playing Bradford Webster, an eccentric and cowardly associate who proved to be an early template for the Dr. Smith persona he would later develop.1 He appeared in two celebrated episodes of The Twilight Zone in 1961: "The Silence" and "Twenty Two."1 In 1963 he played Charles Dickens in an episode of Bonanza.1
The Bill Dana Show (1963-1965)
Harris played Mr. Phillips, a pompous hotel manager, opposite Bill Dana's Jose Jimenez character.1 The role gave him a national audience for his gift for comic pomposity and the catchphrase "Oh, the pain!" -- a line he would carry directly into his next, most famous role.
Lost in Space (1965-1968)
Harris was cast as Dr. Zachary Smith, an enemy agent who sabotages the Robinson family's spacecraft in the CBS series Lost in Space. The character was not in the original 1965 pilot and was added when the network decided the show needed a recurring antagonist.1 Harris was originally contracted for five episodes.1
Midway through the first season, Harris rewrote his own dialogue to shift Dr. Smith from a straight villain toward comedy, correctly reading that broad character work was his strength. Producer Irwin Allen approved and gave him creative latitude over the role. Harris developed Dr. Smith's signature alliterative insults directed at the Robot ("bubble-headed booby," "clamoring clod"), which became cultural touchstones of 1960s American television. Co-star Bill Mumy later said: "He truly, truly single-handedly created the character of Dr. Zachary Smith that we know."2 The series ran 83 episodes across three seasons before its cancellation in 1968, despite fan protests and solid ratings.1
Harris refused a cameo appearance in the 1998 theatrical remake of Lost in Space, stating: "I've never played a bit part in my life and I'm not going to start now."1 However, he made promotional appearances for the film, including reprising Dr. Smith in the television special Lost in Space Forever, appearing on the cover of TV Guide with surviving castmates, and visiting Late Night with Conan O'Brien in character.1
In late 2002, Harris and surviving castmates were in pre-production on an NBC two-hour reunion movie, Lost in Space: The Journey Home, when his death brought the project to an end.1
Later television and film
After Lost in Space, Harris guest-starred across a wide range of television productions including Get Smart, Bewitched, Sanford and Son, Fantasy Island, and Night Gallery. He starred in Irwin Allen's Land of the Giants (1970) and the children's series Space Academy and Uncle Croc's Block in the mid-1970s.1 He served for years as Chuck Norris's vocal coach; Norris credited Harris with teaching him how to project and speak on camera.1
Voice acting
Harris spent much of his later career as a voice actor, exploiting the elaborate diction and theatrical villainy he had refined over decades. Notable credits include:
- Battlestar Galactica (ABC, 1978-1979): Lucifer, a Cylon antagonist (9 episodes, uncredited)3
- Visionaries: Knights of the Magical Light (1987): Mortdredd3
- Darkwing Duck
- Rainbow Brite
- Spider-Man
- Superman: The Animated Series
- A Bug's Life (Pixar, 1998): Manny the praying mantis3
- Toy Story 2 (Pixar, 1999): additional voice work3
- Buzz Lightyear of Star Command
- Freakazoid! season two: Professor Jones, a butler figure openly modeled on Dr. Smith
His final recorded performance was in the animated short The Bolt Who Screwed Christmas, completed before his death and released posthumously in 2009.3
Extreme Ghostbusters
Harris voiced the demon Duophanes in the Extreme Ghostbusters episode "Be Careful What You Wish For" (1997). Duophanes is a wish-granting entity of ancient Greek origin who manifests periodically in human guise, offering to fulfill desires in ways that inevitably cause harm. The role drew on Harris's long-established facility for silky, menacing character work, and his billing as a guest voice actor reflected the prestige the show placed on the casting.
Personal life
Harris married his high school sweetheart, Gertrude Bregman, in 1938.1 They remained married for more than 60 years until his death. Gertrude Harris died on August 28, 2007, at age 93.1 The couple had one child together.
Death
Following hospitalization for a back injury, Harris died of a blood clot on November 3, 2002, in Encino, California, three days before his 88th birthday.1 He was buried at Westwood Village Memorial Park Cemetery in Los Angeles.1
