With a late-20th-century resurgence on television and later screen projects, he remained a respected figure whose work bridged classic stage training with contemporary TV innovation. He is recognised for sustaining a career across multiple media cohorts, and for his longevity in a changing entertainment landscape.

Then & Now The 1980s In the 1980s Daniels became a recognisable prime-time fixture through two very different but equally memorable assignments: the gravel-voiced artificial intelligence KITT in Knight Rider and the principled Dr. Mark Craig on St. Elsewhere. Those roles highlighted his ability to convey authority, wit and warmth, and his Emmy-winning work on St. Elsewhere cemented him as a dependable anchor for ensemble drama. Drawing on a long stage and film background, he helped bridge classical training with the era’s evolving television storytelling. Now (2026) As of 2026 Daniels is largely retired from regular performance, but his influence endures through reruns, the actors he mentored, and the lasting popularity of his signature parts—KITT, Dr. Mark Craig and later Mr. Feeny on Boy Meets World. He is remembered for a career defined by discipline, versatility and moral clarity, sustaining meaningful work across stage, film and television. Daniels’ Emmy-winning performances and longevity remain central to his legacy in American entertainment.
