Walter's long résumé includes Golden-Globe nominated turns as a driver's estranged wife in the race-car drama Grand Prix (1966) and an unstable stalker in Clint Eastwood's directorial debut, Play Misty for Me (1971). She nabbed an Emmy in 1975 for her portrayal of a female chief of detectives in the short-run television series "Amy Prentiss."
Later in life, Walter struck gold doling out throaty insults as self-centered matriarch Lucille Bluth on the critically acclaimed comedy "Arrested Development." The role earned her an Emmy nomination along with multiple Screen Actors Guild ensemble honors.
