Bruce Willis, star of the "Die Hard" franchise, is retiring from acting, his family announced Wednesday.

According to an Instagram post, Willis suffers from aphasia, a language disorder that impairs people's communication ability.

"Bruce has had some health problems and was recently diagnosed with aphasia, which is impairing his cognitive abilities," the post stated.

"As a result of this and after much consideration, Bruce has decided to retire from the career that has meant so much to him."

Aphasia is typically caused by a stroke or head injury, though it can gradually develop in rare cases.

The condition impairs a person's ability to communicate verbally and read and write.

According to the Los Angeles Times, concerns about Willis's short-term memory have recently surfaced.

The newspaper noted that he was not present at Sunday's Academy Awards, which featured several other "Pulp Fiction" stars, including Samuel L. Jackson, Uma Thurman, and John Travolta.

Since the 1980s, Willis has been a fixture on the small and large screen, rising to prominence in the television series "Moonlighting."

However, as the hard-bitten hero John McClane in "Die Hard," he established himself as a bankable major film star, launching a career that has grossed billions of dollars at the box office.

Willis, who turned 67 this month, voiced the infant in the popular family film "Look Who's Talking."

Another of his more well-known roles was the deceased person, who child actor Haley Joel Osment could see in "The Sixth Sense."

Willis has won a Golden Globe and two Emmys throughout his career, but he received a far less deserving honor last weekend — a specially created category in the Razzies for "Worst Performance by Bruce Willis in a 2021 Film."

Willis' current wife, Emma Heming Willis, his former wife, actress Demi Moore, and his children Rumer, Scout, Tallulah, Mabel, and Evelyn, all signed the Instagram post announcing his retirement.

"This is a particularly trying time for our family, and we are incredibly appreciative of your continued love, compassion, and support," the statement continues.

"We are navigating this together as a strong family unit, and we wanted to include his fans because we understand how much he means to you, just as you do to him.

"As Bruce always says, 'Live it up,' and that is precisely what we intend to do."

Fellow celebrities reacted swiftly.

"grace and guts!" Jamie Lee Curtis wrote. "Love to you all," Cindy Crawford wrote on Instagram, alongside praying hands' emojis.

"Sending so much love to you all," actress and former co-star Elizabeth Perkins wrote.
