Watch As An Emotional Mia Farrow Learns Her Family History In 'Finding Your Roots' Clip

We don't see much of Mia Farrow these days. Her most recent on-screen role was in 2012's little-seen "Dark Horse," and Farrow is now more commonly affiliated with international humanitarian work than she is Hollywood glitz. But you'll see her return to television on Tuesday's season finale of "Finding Your Roots."

The Huffington Post has an exclusive clip from the Henry Louis Gates Jr.-hosted PBS docuseries, which explores celebrities' ancestral history. Farrow shares the episode with Dustin Hoffman. Watch below as she learns vital information about her family's World War I roots.
