Celebs find out they aren’t who they think they are

Reality shows generally are not my thing, but this one, I can’t resist. Who Do You Think You Are?, which premieres March 5 on NBC, follows seven celebrities as they find their genealogical roots. Sarah Jessica Parker, Susan Sarandon, Spike Lee, Matthew Broderick, Brooke Shields, Emmitt Smith and Lisa Kudrow are all involved and Kudrow is also executive producer.

The series, which is an American adaptation of an award-winning BBC series that has aired since 2004, takes the stars on a quest to uncover their family trees. Granted, the idea of watching people research their family history sounds like a sure cure for insomnia. But the trailer is irresistible.

OK, what I get from that is that Parker’s related to a witch, Lee’s granddad owned slaves and Sarandon’s grandmother was a, um, “showgirl.” I am so there.

How about you? Does this show look DVR-worthy?
