Friends stars David Schwimmer, Lisa Kudrow and Matt LeBlanc have paid tribute to director James Burrows, describing him as a "father figure".
Burrows, who directed the US sitcom and was also the co-creator of Cheers, died aged 85, with his death announced on Friday.
In a post on Instagram, Schwimmer, 59, who played Ross Geller in Friends, said: "Jimmy Burrows brought out the best in every actor he ever worked with, and elevated every show he directed, making it funnier and more moving than anyone expected.
"His warmth, humility and generosity made us feel safe, like family, and I'm sure we weren't the only cast to feel that way. He looked out for us, on camera and off.
"He became another father figure for me, and I'm sure others.
