Olivia Williams is recalling her time guest starring on "Friends" in 1998.
In a recent interview, the "Crown" actress — who appeared as a bridesmaid in the two-part Season 4 finale titled "The One with Ross’ Wedding" — opened up about her experience on set and explained why her time there was "alarming" and "harrowing."
"Gosh. Well, just as an example, I was taken to the studio in a shared car with a wonderful actress whose character, I think, was called ‘Old Woman,'" Williams told The Independent.

"At one point, a producer — who shall remain nameless — just yelled at her: ‘You’re not funny!’ And she didn’t come back the next day. So that was alarming."
"Oh, and ‘Friends’ was a brand, and you had to fit the brand," Williams, who is gearing up to star in the upcoming Max series "Dune: The Prophecy," added. "You go into hair and make-up and you’re told, ‘There’s a look here. This is what we do.’"
"And that involved, essentially, plucking off all of your eyebrows," she continued. "Literally [I was begging], ‘Please don’t take my eyebrows off, I might need them in another job!’ But yes, that’s the sense in which it was harrowing."
