15 Shows that Replaced Actors and Hoped We Wouldn’t Notice

13. The O.C.

Teen drama The O.C. original cast a very young Shailene Woodley in the role of Kaitlin Cooper, younger sister to Marissa, played by Misha Barton. After just six episodes they replaced her with Willa Holland. No worries; Shailene has gone on to a Golden Globe nomination and roles in the hit Divergent film franchise.

14. Modern Family

Baby Lily in Modern Family was originally played by twins Jaden and Ella Hiller, but then were replaced by Aubrey Anderson-Emmons who still plays the role. Bet you didn’t notice! The twins originally got the role after their parents responded to an ad on Craigslist, but were simply recast because they weren’t having fun.

15. Friends

Ross’ first ex-wife, Carol, was originally played by Anita Barone (in her debut episode) and then by Jane Sibbett, in a reoccurring role, the next seven seasons. Carol left Ross before the first episode of the show after realizing that she was a lesbian, although the couple share a son together, Ben. Carol was just another frequent reminder of Ross’ failed relationships.
