Michael Rosenbaum, Nick D'Agosto

He's baaaaaaack! Nearly a year after bidding Smallville adieu, Michael Rosenbaum has taken a step toward a return to the small screen.

TV's former Lex Luthor has been cast in an untitled NBC comedy pilot from Justin Adler (Samantha Who?), which will revolve around a family. Rosenbaum will play the married middle sibling of three, and a new dad to boot, according to the Hollywood Reporter.

Nick D'Agosto (Heroes) will play kid brother to Rosenbaum.

In other Peacock pilot news, Brit beauty Sophie Winkleman (Ruddy Hell! It's Harry and Paul) has scored the title role in 100 Questions for Charlotte Payne, about a young woman who works at a dating service, while Jaime Lee Kirchner (Dollhouse's Rayna) has nabbed a lead in Mercy, a drama about three nurses.
