 TVLine has reported that actress Christina Applegate will appear as Kelly Summers, an "old high-school flame" of Sanderson. Her character is described as someone who "possesses an appealing, old-fashioned vibe which Dean finds very refreshing."

Kelly is a hipster kind of girl who doesn't own a TV or a computer and prefers to be called "more of a book girl."

"The Grinder" follows the story of Dean Sanderson, Jr. who is an actor in a TV show called "The Grinder" and plays a lawyer. However, when his show is suddenly cancelled, he has no option but to return back to his family.

As soon as he reached home, he found out that his own family members are actual lawyers running an actual law firm. Believing his acting career as a lawyer has given him enough experience, Sanderson decides to become a real lawyer and joins his family.

This would be second venture of Lowe and Applegate together as they both co-starred in 2003 comedy movie "View from the Top" too.

Entertainment Weekly has mentioned that "Entourage" star Emmanuelle Chriqui will also join the cast playing the part of Addison Cross. In the publication, she was described as a "fiery lawyer at Mitch's firm with whom he's having a torrid romance."

Besides Applegate, Natalie Morales, William Devane, Fred Savage, Connor Kalopsis, Mary Elizabeth Ellis and Hana Hayes have confirmed to join the cast as Sanderson's family.
