Bruce Willis is stepping away from his acting career following an aphasia diagnosis, according to an Instagram post by his daughter, Rumer Willis.

The action star is perhaps best known for his role as John McClane in the Die Hard film franchise. "This is a really challenging time for our family and we are so appreciative of your continued love, compassion and support," Rumer wrote.
