We already know that Greta Gerwig will anchor How I Met Your Dad as the flighty, unsure Sally, and now the show has locked in most of the rest of its cast: Masters of Sex's Nick D'Agosto will play Frank, the dorky IT guy who falls for Sally, but D'Agosto is still expected to recur on MoS, thank God. Workaholics' Anders Holm (also recently of The Mindy Project) will play Sally's ex-husband, and Andrew Santino has been cast as Sally's overachieving lawyer brother, though that's in second position to his role as the red-headed rapist on Mixology. They join the previously cast Gerwig and Smash's Krysta Rodriguez, who plays Sally's party-hard BFF. Will the upcoming series finale of How I Met Your Mother forever sour America on love? We shall see.
