Watch Who Do You Think You Are?

Who Do You Think You Are? is a documentary series that is based upon tracking the genealogy of high profile celebrities that airs on the U.S. NBC network station and affiliates. The American show was adapted from the British version that aired on the UK BBC network. The premise of the show each week features a celebrity who embarks upon a journey to various cities and countries, in an effort to trace their family tree.

Lisa Kudrow was the first featured celebrity and an executive producer on the series, as a partnership between Shed Media, and NBC Entertainment. In each episode, family secrets are revealed and information is discovered about their families which sometimes answers and often shocks the celebrities.

Of note is that Ms. Cattrall's episode was an edited version of the original broadcast which aired on the original British series.

The season will feature the following 12 celebrities: Oscar winning actress, Marisa Tomei; actor and writer, Rob Lowe; chef and show host, Paula Deen; actress, comic book author, singer and screenwriter, Rashida Jones; retired American NFL football halfback, Jerome Bettis; country singer and actress, Reba McEntire; Emmy winning actress, Helen Hunt; Emmy winning actress, Edie Falco; actress and producer, Rita Wilson; comedian, actor and writer, Jason Sudeikis; actor, producer and political activist, Martin Sheen; and actor, Blair Underwood.
