Robin Williams and Sarah Michelle Gellar, The Crazy Ones
How You Know Them:This is Williams' first return to series television since he played a fun-loving alien on Mork and Mindy, but his movie career includes such films as Good Will Hunting, Mrs. Doubtfire and Dead Poets Society. Gellar's iconic role is the titular heroine of Buffy the Vampire Slayer, though she also recently starred (as twins!) on the ill-fated 2011 series Ringer.
The New Roles: Williams and Gellar play a father-daughter team who work at an advertising firm. Gellar's used to being a leading lady, but she'll have to settle for more of a supporting role here, thanks to Williams' outsize personality. Look for Williams to employ his typical one-man-comedy-act shtick, with Gellar acting as the straight woman to his frenetic goofiness.
