'Friends' Star James Michael Tyler Explains Not Revealing Cancer on Reunion - TMZ
"Friends" star James Michael Tyler -- who famously played Gunther -- says keeping silent about his stage 4 cancer diagnosis during the reunion show was the right thing to do for the show's fans and his costars.
James says the producers of the show have known about his diagnosis for a long time -- but it sounds like the cast didn't know during the taping, but said they know now.
