How I Met Your Mother spinoff 'How I Met Your Dad' casts Anders Holm, Nick D'Agosto and Andrew Santino

The How I Met Your Mother spinoff entitled How I Met Your Dad has added more actors to round out the cast, including Anders Holm of Workaholics and The Mindy Project. Holm will play the recurring role of Gavin, the soon-to-be ex-husband of main character Sally (Greta Gerwig), according to an exclusive report from TVLine.

Nick D'Agosto (Masters of Sex) has also joined the cast as Frank, the head of IT for Juliet's (Krysta Rodriguez) fashion blog. Finally, Andrew Santino will guest star in the pilot as Sally's older brother Danny, an uptight lawyer. Santino's role on HIMYD is secondary to his role on ABC's Mixology, which has yet to be renewed.

Sally is the new Ted Mosby character. She is a colorful, messy and unpredictable character and the casting info describes her as a "female Peter Pan who has never grown up and has no idea of where she's going in life." She's on the verge of getting divorced from her current husband of one year, Gavin, when the show begins, and she'll turn to her group of friends for advice and support.

First on that list of friends is Juliet (Rodriguez), who sounds like the Barney of the group. She is a "sexy, flamboyant, energetic party-girl BFF," according to TVLine. She runs her own successful fashion blog and is happy to know Sally is breaking up with Gavin, whom she finds boring.

Danny (Santino) is Sally's gay older brother and an overachieving brother with a Type A personality. The two have little in common but are very close. Sally moves in with Danny after the divorce, which could strain their relationship.

But Danny's husband, Todd (Drew Tarver), is warm and outgoing and one of Sally's best friends from college. He is thrilled to have Sally in their home.

Frank (D'Agosto) is the head of IT for Julie's blog and a hot nerd. He has true feelings for Sally but they are not returned, at least at the start of the show.

And then we have the Narrator, aka Future Sally, who is telling the story to her children.
