'Catastrophe' Star Sharon Horgan Shares Heartwarming Message About Carrie Fisher In Her Final Role

You might have thought that Carrie Fisher's last role was playing General Leia Organa in the Star Wars franchise, but it wasn't. Fisher had actually been working on a Channel 4/Amazon comedy series called Catastrophe.

Fisher had been in London filming the show a week before her passing on December 27, 2016. She had the role of a cranky, and rather mean, mother-in-law to co-star and co-creator Sharon Horgan. In the show, Horgan and Fisher don't get along too well, but it's clear from Horgan's touching and heartwarming Instagram message that was not the case in real life.

Horgan recently posted two photos of Fisher. One was a week before she passed of Horgan, Fisher, and co-star/co-creator Rob Delaney, who played Fisher's son on the show. The second photo was of Horgan getting a loving hug from Fisher, while on set.

Carrie was my friend. It took me three series but I got her in the end. She was the most generous, fun, gifted, smart, kind, funny funny funny person I've ever met. She certainly wasn't ready to go. I'm so glad we became pals. I'm so devastated at her loss. I want to write about her more but I can't process yet.

"Carrie was my friend. It took me three series but I got her in the end," Horgan captioned the photo of her and Fisher on set. "She was the most generous, fun, gifted, smart, kind, funny funny funny person I've ever met. She certainly wasn't ready to go. I'm so glad we became pals. I'm so devastated at her loss. I want to write about her more but I can't process yet."

Horgan and Delaney knew that they wanted to cast Fisher in the part of Rob's "rough around the edges" mother after seeing her present at the Attitude Awards.

"I turned to Rob, and I went, 'That's your awful mother!'" Horgan recalled. "We still to this day can't believe that [Fisher] said yes."

During an interview about the show, Fisher explained why she decided to play the part of the awful mother. She said, "I did really want to play an awful person. There are not a lot of choices for women past 27. I don't wait by the phone."

Fisher will be forever missed by her fans but can be seen in her role as Rob's mother, Mia in season three of Catastrophe when it airs next year.
