Big Bang Theory Casting Scoop: Look Who's Playing Bernadette's Father!

Howard Wolowitz, meet your future father in law.

The Big Bang Theory has tapped acting vet Casey Sander (Grace Under FireJustified) to guest star as Bernadette’s (Melissa Rauch) blue-collar ex-cop dad.

Sander first appears in the May 3 episode, “The Launch Acceleration,” which deals with the potentially catastrophic fallout of Howard’s delayed NASA mission. Basically, the new launch date conflicts with his wedding to Bernadette – putting their big day in jeopardy.

Perhaps Mr. Rostenkowski shows up to help Howard get his priorities in order?

The gig reunites Sander with his former Grace Under Fire boss (and Big Bang EP) Chuck Lorre.
