William "Bill" Zuckert (18 December 1915 – 23 January 1997; age 81) was a New York-born actor who played Sheriff Johnny Behan in the Star Trek: The Original Series third season episode "Spectre of the Gun".
Zuckert's career extended nearly half a century. Besides his stint on Star Trek, he has also made guest appearances in such classic television series as The Honeymooners, Gunsmoke, My Favorite Martian (starring Ray Walston), Family Affair (starring Brian Keith), Bewitched, Barnaby Jones (with Lee Meriwether), Maude (with Adrienne Barbeau), Mary Tyler Moore, and Quincy, M.E. (with Robert Ito and Garry Walberg). He also had a one-year stint as Arthur Bradwell on the Emmy-nominated series Mr. Novak (1964-65). Fellow TOS guest stars Jeanne Bal and Vince Howard were also regulars on this program, while Malachi Throne and Walter Koenig were frequent guest stars.
One of his earliest film roles was an uncredited appearance as a bartender in the 1959 film-noir Odds Against Tomorrow, directed by Robert Wise. Other film credits include The Cincinnati Kid (1965, with Jeff Corey, Ron Soble, and Robert DoQui), Hang 'Em High (1968, with Mark Lenard and Paul Sorenson), The Great Bank Robbery (1969, with Elisha Cook, Jr. and John Fiedler), Hangar 18 (1980, directed by James L. Conway and featuring William Schallert), and Ace Ventura: Pet Detective (1994, with Noble Willingham and Mark Margolis). His final film appearance was as a gigantic mutant old man in "Geriatric Park", a short skit spoofing Jurassic Park in 1994's The Naked Gun 33 1/3: The Final Insult. Star Trek: Deep Space Nine actor Marc Alaimo and Star Trek: The Next Generation guest star Bill Erwin also appeared in this film.
A cancer-stricken Zuckert died from pneumonia in Woodland Hills, California on January 23rd, 1997. He was 81 years old.
