Hollywood is mourning James Burrows, the legendary sitcom director whose work defined the greatest comedies ever made. The Cheers co-creator died Friday at age 85 following a brief illness.

Tributes are coming from the stars who worked under his direction. Lisa Kudrow, Ted Danson, Danny DeVito and more have called him "the greatest of all time," celebrating a man who essentially wrote the playbook for how to make a sitcom.

Burrows' work shaped some of television's most iconic shows. Beyond Cheers, he directed episodes of Friends, Will & Grace, Frasier, and countless others that defined entire generations of TV viewers.

For decades, he was the go-to director when networks wanted laugh lines, perfect timing, and performances that felt effortless even when they required surgical precision. He made directing sitcoms look easy — it wasn't.

The multi-cam sitcom format owes much of its appeal to Burrows' mastery. He understood how to stage a scene for three cameras, how to pace a joke, and how to get the best out of his ensemble casts. His technical brilliance matched his warmth on set.

Colleagues remember a generous mentor who helped shape careers and brought out the best in everyone around him. For generations of writers, actors, and producers, working with James Burrows was a master class.

The entertainment community will remember Burrows as a titan of television — a man who made the sitcom format an art form.
