Michael Douglas discovered a fellow actor is also a distant relative: Scarlett Johansson. On the PBS show Finding Your Roots, host Henry Louis Gates Jr. revealed that Scarlett is a “DNA cousin” of Douglas. “Are you kidding?” asked Douglas on the show. “Oh, that's amazing. All right. This is cool. This is so cool.” According to Gates and his "book of life" containing research from professional genealogists, Douglas and Johansson “share identical branches of DNA on four different chromosomes.” The two actors’ branches of shared DNA “appear on Scarlett's maternal lines, which stretch back to Jewish communities in Eastern Europe,” Gates explained to Douglas.
