Here's what some of the cast and crew of Curb had to say about Tracey...
"Tracey has a pretty significant role this season. It's amazing she hasn't been on the show already. Working with her was a masterclass. On set, she made it her job to crack Larry up, and she was successful in making him blow takes in almost every scene."
– Jeff Schaffer, executive producer of Curb Your Enthusiasm
"I did a whole bunch of stuff with Tracey Ullman. I absolutely loved working with her ... She’s in a few different episodes. That was just a dream. I’ve never met her before. She's so committed and she has no vanity whatsoever."
– Susie Essman (as "Susie Greene")
"Tracey Ullman is like bringing in Sarah Vaughn! She was the highlight of the season for me." – Jeff Garlin (as "Jeff Greene")
