Mark: (On his most memorable moment filming Glee) I can think of two moments. One moment would be shooting a scene with Kristen Chenowith where she is singing. I was sitting right in front of her and she was just belting it out. She can let loose like no other! She's singing a song and it was pretty much directly to me. I was sitting right in front of her and she was singing it to the group of people I was in. It was one of those moments where I thought, "Wow! How did I end up here?" She is so beautiful and talented.
