Exclusive: NBC's Grimm Casts E.T. Mom, Friday Night Lights Coach as Monroe's Parents

We’re about to find out whether or not the Blutbad falls far from the tree: Grimm has cast Monroe’s parents.

Dee Wallace (E.T. the Extraterrestrial) and Chris Mulkey (Friday Night Lights) will play the Wesen’s mom and dad, Alice and Bart, later this season, TVLine has learned exclusively.

Before the season began, series co-creator/executive producers David Greenwalt told TVLine that the clock enthusiast’s folks would make an appearance related to Monroe and Rosalee’s much buzzed-about wedding.

“They’re a little old-fashioned,” Greenwalt warned, implying that Monroe’s purist folks may not like the idea of their son being romantically involved with a Fuchsbau — and friends with a Grimm.

We hear that Monroe has to convince his parents to open up to his way of life or risk destroying his relationship with them.

Wallace is best known as Mary, mother of the E.T.-loving Henry in Steven Spielberg’s 1982 sci-fi hit. Recently, she’s appeared on Switched at Birth, Warehouse 13 and The Office.

Mulkey played FNL‘s Coach Bill McGregor — aka the man who briefly replaced Coach Taylor in Season 2. His extensive TV credits include  The Mentalist, Saving Grace and Boardwalk Empire.
