The 48-year-old actress, who played the role of a divorced mother, said that the show had some charm left after it ended last year, reported Contactmusic.
"I certainly would be up for it. I never felt like all the stories were done when it wrapped up. I felt like it still had life," she said.
The actress however seemed unsure of what unfinished business was left for her role.
"Of course, they killed Mike. I don't know what the story would be for Susan and how she could divorce herself from the sadness of how that ended for her. Maybe the movie would be before Mike died."
