Stacy Keach, the stage and screen actor best known as TV private eye Mike Hammer, died on Tuesday, Nov. 10, at his family home in Magdalenka, Poland. He was 85. His wife, Malgosia Tomassi Keach, said in a statement that he died “after a long and difficult battle with a serious heart condition and heart failure,” according to Variety and USA Today. For anyone asking what happened to Stacy Keach, the family has named heart failure, and no other cause has been reported.
What his family said
The announcement came from Malgosia Tomassi Keach, whom he married in 1986, according to Variety. Several outlets received the same statement, including Variety, USA Today and Fox News. “Stacy peacefully departed this world,” she wrote. “He fought for so long, with extraordinary courage, determination and strength. He was a true warrior, facing his illness with the same remarkable spirit and resilience that defined his life.”
She also called him “my beloved husband, my companion and the heart of our family” and said “his unforgettable voice and the love he gave so generously will remain with us forever.” The statement did not mention funeral or memorial plans. He is survived by his wife, their children Shannon and Karolina, grandchildren and his brother, the actor and director James Keach, per Variety and Rolling Stone.
His heart trouble, from 2017 to this week
Keach’s health problems were public for almost a decade. In 2017 he had a heart attack onstage during the opening night of “Pamplona,” a one-man play at Chicago’s Goodman Theatre in which he played Ernest Hemingway. The Associated Press and Fox News both reported the episode, and Fox said it forced the cancellation of the run.
He described that night himself in a 2018 essay for The New York Times, quoted by USA Today. “It resembled a fog rolling in, causing me to completely lose track of where I was in the dialogue,” he wrote. Tests the next day showed a mild heart attack and badly clogged arteries, and he had a six-hour triple bypass operation. By 2018 he wrote that his health had “never been better.” His wife’s statement does not say when the heart failure was diagnosed.
A career that started on the stage
Keach was born in Savannah, Georgia, to actor and drama teacher Stacy Keach Sr. and actress Mary Cain Peckham. He graduated from the University of California, Berkeley, and earned a graduate degree at the Yale School of Drama, Variety and USA Today reported.
The theater made his name before TV did. He earned a Tony nomination for playing Buffalo Bill in Arthur Kopit’s “Indians,” which opened on Broadway in 1969, and he played Hamlet, Richard III and King Lear over the following decades. Rolling Stone noted Helen Hayes Awards for “Richard III” and “Macbeth” with the Shakespeare Theatre Company and his 2015 induction into the American Theatre Hall of Fame.
On film, he played the fading boxer in John Huston’s “Fat City” (1972), and he and his brother James played the outlaw brothers Frank and Jesse James in “The Long Riders” (1980). He also turned up in the Cheech and Chong comedies “Up in Smoke” and “Nice Dreams” as Sgt. Stedenko, the narcotics officer, USA Today noted.
Mike Hammer, the 1984 arrest and the comeback
Keach first played Mickey Spillane’s detective in a 1983 TV movie, USA Today reported. “Mike Hammer” then ran on CBS from 1984 to 1987, according to Variety and Rolling Stone. He came back for the 1989 TV movie “Mike Hammer: Murder Takes All” and for the syndicated “Mike Hammer, Private Eye” in 1997 and 1998.
The AP noted that his career was nearly derailed in 1984. That year, police at London’s Heathrow Airport arrested Keach for bringing cocaine into Britain, and he went to prison after pleading guilty, Variety and the AP reported. USA Today put the amount at 1.3 ounces. Variety said he later called that period the low point of his life and that a friendship with a priest in prison led him to convert to Catholicism. The AP said he went on to speak about drugs at colleges and rehab centers.
His performance as Ernest Hemingway in the 1988 TV production “Hemingway” won him a Golden Globe, Rolling Stone and Fox News reported, and Variety noted it also brought an Emmy nomination.
