"The Big Bang Theory" features some unexpectedly emotional moments, such as one in season 6 where Penny casually tells Leonard Hofstadter that she loves him for the first time.
"It just was so perfect, Steve and Chuck came out and said, 'We're going to move on. We don't want to touch that.'" Cuoco also confirmed that she cried for real during filming.
She said, "I cried at the table read. I cried in the rehearsal. I cried in run-throughs." She also added, "It was really the first time I felt like I was actually in that moment."
