Sarah Braverman – Parenthood

Maura Tierney was never officially on the hit show Parenthood. But actually, the News Radio and ER actress was originally cast as Sarah Braverman in the pilot episode, but it never aired.

Tierney ended up withdrawing due to health reasons and was replaced by Gilmore Girls’ Lauren Graham. In a sweet twist, Graham ended up finding love in real life with Peter Krause, who portrayed her brother Adam Braverman on the show.
