TV actress Ellie Kemper

Ellie Kemper made a big splash when she joined the cast of NBC's sitcom "The Office" in 2009.

She debuted as Erin Hannon, a nice, bubbly receptionist whose sweetness stood in stark contrast to the other characters in the Scranton, Pennsylvania-based sitcom about a paper supply company.  Erin even liked the least likable of her coworkers, including the very nasty Dwight Schrute.  Ms. Kemper played the role for the reminder of the series' run through 2013.

More recently, she has played the title role in an acclaimed sitcom called "Unbreakable Kimmy Schmidt," in which she plays the title character.  Kimmy is a young woman from Indiana who, along with three other women, has been rescued from a doomsday cult after fifteen years of being held captive and locked away from the outside world.  She moves to New York City to start her life over with nothing more than positive attitude and ultimately gets a job as a governess for a disconnected socialite while befriending her street-smart landlady and rooming with an aspiring actor.  Really.

If you haven't seen "Unbreakable Kimmy Schmidt" in your local TV listings, that's because it's a Netflix show.  Its final season just wrapped up.

Ellie Kemper has been a TV star for a decade at this writing.  In an age where TV stars are roosters and hens one day and feather dusters the next, it would appear that Ms. Kemper is as unbreakable as Kimmy Schmidt. :-)
