#13: Marlo Thomas, Meeting Rachel’s Mom
Long before Carrie Bradshaw, there was Ann Marie. Marlo Thomas starred in That Girl (1966–1971) as a young woman chasing her acting dreams in New York City. She was single and independent, and that was a pretty big deal for TV in the ’60s.

In 1996, she popped up on Friends as Sandra Green, Rachel’s mom, and earned an Emmy nomination. Millions of younger viewers suddenly knew her name. She’s also raised huge sums for St. Jude Children’s Research Hospital. It was a delightful return, just a short one.
