Off-screen troubles
Tierney's numerous arrests for being drunk and disorderly, and jail terms for assault on civilians and police officers alike, took a toll on his career. He was an admitted alcoholic who tried to go sober in 1982 after having a mild stroke, once observing during a 1987 interview that he "threw away about seven careers through drink".
Between 1944 and 1951, Tierney was arrested at least twelve times in Los Angeles for brawling—fistfighting with multiple people—and frequently for drunkenness which included ripping a public telephone off a wall in a bar, hitting a waiter in the face with a sugar bowl for refusing to serve him any more drinks, and attempting to choke a taxi driver. He was jailed for three months for brawling in May 1947 and again in June 1949 and drunkenness in January 1949 and October 1950. His legal troubles included a 90-day jail sentence which he served from August to October 1951 for breaking a New York college student's jaw during another barroom brawl. He served 66 days in the city jail in Chicago, Illinois from March to May 1952 on drunk and disorderly charges. In October 1951, he was sent to a mental hospital in Chicago after being found in a church in a disheveled state. In New York City, he was arrested for assault and battery of a barroom pianist in August 1953, and in October 1958 for resisting arrest and assaulting two police officers in another barroom brawl. At the time of his October 1958 arrest outside a Manhattan bar, The New York Times reported that he had been arrested six times in California and five in New York City on similar charges.
In January 1973, he was stabbed in a bar fight on the West Side of Manhattan. Two years later, Tierney was questioned by New York City police in connection with the apparent suicide of a 24-year-old woman who had jumped from the window of her high-rise apartment. Tierney told police, "I had just gotten there, and she just went out the window." He was never arrested or charged with the young woman's death.
In July 1991, during the filming of Reservoir Dogs, Tierney shot at his nephew in a drunken rage at his Hollywood apartment, and was arrested and jailed. He was released for one day to continue filming, as recounted by the film's director Quentin Tarantino in an interview. Tarantino never again worked with or hired Tierney to act in his films.
Tierney's Reservoir Dogs co-star Chris Penn recounted an incident in which Tierney, for no apparent reason, stole a table lamp from a restaurant where they had eaten, and showed it off to Penn while the two drove in Penn's car.
Wil Wheaton recalled that while filming Season 1, episode 12 of Star Trek: The Next Generation in October 1987, Tierney questioned why the 15-year-old Wheaton did not play football in school and belittled him with homophobic slurs.
The Simpsons showrunners and writers Josh Weinstein and Bill Oakley stated on Twitter numerous incidents regarding Tierney's voice recording session for the show in 1995, including "terrorizing" the writers and staff, sexually harassing the female casting director and making strange demands for his role, such as insisting he voice the entire performance with a Southern accent.
In December 1990, during the filming of Season 2, episode 3 of Seinfeld, Jason Alexander and Jerry Seinfeld caught Tierney in the act of trying to steal a knife from the set. When Seinfeld confronted him, Tierney began to laugh nervously and jokingly pretended he would stab Seinfeld while imitating the music from the film Psycho. Tierney’s role was intended to be reoccurring on the show but after the incident, the entire crew was uncomfortable with Tierney, prompting Seinfeld not to hire him again. Julia Louis-Dreyfus complimented Tierney's performance on the show but stated he was a "total nutjob.”
