Hayley Atwell Surprises Fan Dressed As Agent Carter

Marvel actress Hayley Atwell (Captain America: The First Avenger) surprised a fan dressed as her character Peggy Carter at San Diego Comic-Con!

Agent Carter super-fan Jovanie Seghers-Narvaez had the best day of her life at Comic-Con when Hayley Atwell snuck up on her and said hello. James D'Arcy (Jarvis) was also there, but he was off camera shooting the actual video.

"I'm the girl in video! And believe me it was the greatest thing that's ever happened to me! Hayley and James were both so delightful and it was so great of them to come say hi," Jovanie Seghers-Narvaez wrote on facebook. "Best day of my life."

Jovanie doesn't know how she was able to appear calm during those initial moments. "Don't worry, you guys, I TOTALLY lost it afterwards," she revealed.
