Career
Astin started his performing career in theater, making his first Broadway appearance as an understudy in Major Barbara (1954) and also did voice-over work for commercials. Astin appeared as "Ready-Money Matt" in the long-running off-Broadway production of Threepenny Opera (which began in 1954), starring Lotte Lenya. His first big film break came with a small role in West Side Story (1961), followed by roles in That Touch of Mink (1962), Move Over, Darling (1963).
During this period, Astin's talent for also playing comedy was spotted by actor Tony Randall, leading to guest starring roles on the sitcom Dennis the Menace, starring Jay North; The Donna Reed Show; and Harrigan and Son, starring Pat O'Brien, the first show broadcast on CBS and the latter two shows broadcast on ABC. In 1961, Astin appeared in the final episode of the ABC police drama The Asphalt Jungle. On April 7, 1961, he played the role of Charlie in the Twilight Zone episode, "A Hundred Yards Over the Rim" which starred Cliff Robertson.
During the 1962–63 television season, Astin had his first lead in a television series, the ABC sitcom I'm Dickens, He's Fenster, co-starring with Marty Ingels. Astin played Harry Dickens to Ingels's Arch Fenster, as two trouble-prone carpenters. The series combined witty dialogue with moments of slapstick comedy. I'm Dickens, He's Fenster received critical raves, but was against two high-rated shows, Sing Along with Mitch on NBC and Route 66 on CBS. By the time I'm Dickens, He's Fenster gained a following and started winning its time slot, ABC had already canceled the show. A total of 32 episodes were produced.
Astin is widely known for The Addams Family, a popular sitcom that ran on ABC from 1964 to 1966, based on cartoons created by Charles Addams. Astin starred as Gomez Addams, the head of the macabre family. He later reprised the role of Gomez in the 1977 made-for-television film Halloween with the New Addams Family and voiced the role of Gomez in the animated series The Addams Family from 1992 to 1993. In the Canadian-American television series The New Addams Family, which ran from 1998 to 1999, Astin appeared as Grandpapa Addams, with the role of Gomez played by Glenn Taranto. With the death of Lisa Loring, who played Wednesday, as of January 2023, Astin is the last surviving cast member of The Addams Family.
Astin joined the retooled The Pruitts of Southampton (re-titled The Phyllis Diller Show) for the second half of the 1966–67 season, playing Diller's brother-in-law, Angus Pruitt. He also played the Riddler in the second season of Batman (Frank Gorshin returned for the third and final season.)
Astin portrayed the title character in the television film Evil Roy Slade (1972), starred as Bill Andrews in the film Freaky Friday (1976), and played submarine commander Matthew Sherman on the 1970s television series Operation Petticoat. He also made several appearances in the first two seasons of the popular mystery series Murder, She Wrote, as scheming real estate developer (and finally Sheriff) Harry Pierce, who ends up as the murderer in his last episode. He had a recurring role on the sitcom Night Court as Buddy Ryan, an eccentric former mental patient later revealed to be Judge Harry Stone's biological father; Buddy often ended his conversations with a big smile and the phrase,"...but I'm feeling much better now!"
Astin appeared in the films National Lampoon's European Vacation (1985), and Teen Wolf Too (1987). He played the regular role of Ed LaSalle on the short-lived Mary Tyler Moore sitcom Mary during the 1985–86 television season. He also guest starred on numerous television series, including appearances on Duckman, Homeboys in Outer Space, Jack Palance's ABC circus drama The Greatest Show on Earth, and a 1967 episode of Gunsmoke as Festus Haggen's cousin Henry.
Astin received an Academy Award nomination for Prelude, a short film that he wrote, produced, and directed. He was nominated for an Ace Award for his work on Tales from the Crypt, and received an Emmy Award nomination for the cartoon voice of Gomez on ABC-TV's The Addams Family. He also voiced the character Bull Gator on the animated series Taz-Mania. Astin served for four years on the board of directors of the Writers Guild of America, and has been active in community affairs in Los Angeles and Santa Monica.
Astin has continued to work in acting, appearing in a string of Killer Tomatoes films as Professor Gangreen and as Professor Wickwire in The Adventures of Brisco County, Jr.. In 1996 he featured as The Judge, the ghost of an Old West gunslinger, in Peter Jackson's The Frighteners. He also has toured the one-man play Edgar Allan Poe: Once Upon a Midnight, written by Paul Day Clemens and Ron Magid. In a December 2007 Baltimore Examiner interview, Astin said of his acting experience:
We all struggle, and I had plenty of that, but I've had a great time. I've done hundreds of TV shows and 30 to 40 movies, and I love acting. I'm very happy having done the Poe. That's been really terrific.
Astin is a member of the board of directors of the Columbia Center for Theatrical Arts in Columbia, Maryland.
