Karen was originally meant to be Grace's friend from work. She would interact with Grace, possibly Will. While Jack would interact almost solely with Will. Jack and Karen would never meet. However, when the producers realized what chemistry Megan and Sean had, they decided to make Karen and Jack meet.
Will originally had a partner, Higgins, but his scenes were deleted in the final draft of the script.
Staff writer Ellen Idelson supplies the voice of Will's secretary, Ellen.
Jimm Ginnini is credited, but his scene was deleted during editing. He is Grace's builder, who created an over-stuffed chair for her.
The show is inspired by showrunner Max Mutchnick (who is gay in real life) and his relationship with his best friend, a woman named Janet.
