Richardson-Whitfield will play Mrs. Denby, the wife of Mr. Denby, played by Greg Comer. Mr. Denby is a charismatic hedge fund guy who recently loses everything due to fraudulent investments. He brings his wife to the trailer park for a new start. Whitfield's character, unhappy with her new life, becomes Barr's foil.
According to the Deadline report, the original casting director Risa Bramon Garcia had in mind a non-ethnic character for the role originally, and suggested trying Richardson for the part.
I don't know about you, but this plot sounds hilarious to me. I'm happy for Richardson; her Syfy series Eureka, which she worked on for five years, was cancelled back in August of last year.
