Estelle Harris was perfectly cast as Seinfeld's Estelle Costanza on Seinfeld -- visually and temperamentally

The Boston Globe

"She was a yeller, which made her half of a perfect team with Jerry Stiller as her husband, Frank, who could also work up a good tirade," says Matthew Gilbert in an appreciation of the actress who died Saturday at age 93. He adds: "In looking over Youtube clips from Harris’s tenure on Seinfeld, her magic is clear. She was doing the thing that Susie Essman later took on and mastered on Curb Your Enthusiasm, with direct, unedited expressions of frustration and judgment and the ever-scanning eye looking for slights. It’s the kind of comic effrontery that’s at the core of Seinfeld."
