From Executive Producer Lisa Kudrow (“Friends,” “The Comeback”) — in conjunction with her production company Is or Isn’t Entertainment and the U.K.’s Wall to Wall productions, “Who Do You Think You Are?” is an adaptation of the award-winning hit British television documentary series. The seven-episode program will lead celebrities on a journey of self-discovery as they unearth their family trees that reveal surprising, inspiring and even tragic stories that are often linked to crucial events in American history.

In the seventh and final episode, writer/producer/director, Spike Lee aims to find out more about his mother’s side of the family, as he is already quite aware of his father’s side. Lee’s mother passed away at a young age which led Lee to be raised by his Grandmother who passed away a few years ago. Even though he didn’t use his skills to document his Grandmother’s journey, he did take a DNA test a few years ago to find out where his family came from. This brings him one step closer to finding out the most about his family roots. So Lee leaves New York and begins his journey in his hometown of Atlanta, Georgia to meet with a genealogist who specializes in African American Ancestry. The help that Lee gets along the way leads him to finding his Great Great Grandmother’s obituary! This was the key in moving further in Lee’s search as he finds out about other family members that he never knew about. There’s an interesting Mars connection between Lee’s film, “She’s Gotta Have It” film and his family that shocked even Lee. Even more shocking was being able to trace back not just his family but those who owned his family and visiting the land that Mars owned. The journey for his ancestors has been quite an incredible one. There’s lots more to discover in this episode, including one unfortunate twist of fate for Lee’s Great Great Great Grandfather. The episode ends with Lee making a visit to his distant cousin…but not just any cousin, a descendant of the slaveowners. To see how this meeting went, you’ll have to tune in! This was quite a fascinating and eye opening journey to watch and one that will make you really appreciate what those before you went through. Make sure to tune in because you will learn a thing or two.

Who Do You Think You Are? airs Fridays at 8/7c on NBC.
