It can seem like Hollywood is all glitz and glamour, but while the idea of being famous is appealing to many of us, a lot of real, hard work goes into movies behind the scenes. That work can test a person’s limits not just as an actor but as a human being.

Lauren Cohan in the Walking Dead

The Walking Dead nearly suffered what would have been a devastating loss in Season 3, when Lauren Cohan, who plays Maggie, contemplated quitting over a particularly stressful scene.

After reading the script and realizing Maggie was supposed to perform an emergency c-section on another character, she took her concerns to co-star Steven Yeun, explaining she was worried it would be too intense—yet after further consideration, that’s exactly why she decided to stay.

Recognizing that TWD is a show about people pushed to grueling extremes, she drew on her discomfort to deliver an affectingly honest performance.
