"I just heard the shitty news about Jessica Walter an absolutely brilliant actress and amazing talent," wrote David Cross, who starred as Lucille's son-in-law Tobias Fünke.

Similarly, Will Arnett, who played Gob, Lucille's eldest son, called Walter a "deeply talented person." He added, "We first met on a pilot in '96 and I was instantly blown away. I'm fortunate to have had a front row seat to her brilliance for 25 years. My thoughts are with her daughter Brooke and grandson Micah today. Farewell Jessica, you'll be missed."

"What an incredible career, filled with amazing performances," tweeted Jason Bateman, who starred as Michael Bluth, another son of Walter's character. "I will forever remember my time with her, watching her bring Lucille Bluth to life. She was one of a kind.”

Alia Shawkat, who portrayed Maeby Fünke, Lucille's granddaughter, posted a throwback photo of Walter, writing, "💔love you Gangie #jessicawalters.

"Arrested Development" writer and producer John Levenstein tweeted, "Jessica Walter never missed. If she didn't get a laugh there was a problem with the script."

Meanwhile, Walter's "Archer" family also paid tribute.

"I was so lucky to have had the opportunity to work with and know Jessica," wrote Walter's co-star Amber Nash, who shared a photo of herself and Walter on Instagram. "She was the best of us.

"Archer's" network FX released a statement: "We are utterly heartbroken to learn of the passing of Jessica Walter. She was a comedic genius and a brilliant actor who personified wit, grace and elegance."

"Jessica's 'Malory Archer' served as the bedrock character for the series and we were always honored to have her as member of our FX family," the message continued. "Words cannot describe the monumental loss we and the 'Archer' producers and cast feel. We extend our love, appreciation and condolences to Jessica's family.”

Adam Reed, creator and executive producer of "Archer," also shared a statement of his own.
