Modern Family

Nathan Lane, Elizabeth Banks, Fred Willard... Danny Trejo?!?

The latter doesn't exactly fit into the comedic mold of most Modern Family guest stars, which just has us that much more interested in seeing this actor take on the role of a janitor later this fall.

Almost always playing a villain on the big screen, Trejo (who really did serve 11 years in jail) will come aboard the ABC smash on an episode that finds Claire in charge of a school dance. Look for her to form an unlikely bond with Trejo's scary employee.

In other Modern Family casting news, Mary Lynn Rajskub will guest star as Mitchell's high school girlfriend.
