Teenage TV Characters Who Were Actually Adult Actors

Meredith Monroe played high school student Andie McPhee on teen drama Dawson's Creek. As Insider pointed out, Monroe was significantly older than the character she portrayed, given she was 28 at the time and Andie was 16.

Despite being older than her cast mates, McDowell recalled her first day on the set as being "nerve-wracking." As she told Entertainment Tonight, she recalled being "giddy with excitement" when she landed the role, but began "freaking out" as she flew to the set in North Carolina. 

What really freaked her out was the weird reception she received from new co-star Katie Holmes. Recalling that James Van Der Beek, Michelle Williams, and Joshua Jackson were all "amazing" to her, she said, "Katie really gave it to me." Monroe explained, "She said, 'Oh yeah, you know we had somebody come in last year and they were going to be a new series regular, but we got rid of them after one or two episodes.' I was like, 'What?' She said, 'I'm just kidding! What do you want to drink?' and I was like, 'Oh my god, my heart just stopped.'"
