Tom Hanks interprets a middle-aged man who is always depressed and caring for his son. He said, "Generally speaking, romantic comedy means that someone will spend a long time designing my hair, but all I do is show up, and Nora will do the rest." He said Cooperating with director Nora is very easy. "Working with Nora is like attending a banquet she held. There are a lot of great conversations. Although sometimes you are fooling around, in general you just have to follow Nora’s ideas. Just let you say what you say. The scenes of the movie are very real, and I don’t even feel that I’m working. So the performance is very few, and everyone is very real.”
Meg Ryan believes that romantic comedies are a more difficult type to act. "Because romantic comedies are not dramas and cannot be reproduced in the real world; they are not farce, and they cannot be performed in the direction of making everyone hilarious. They are in the middle. A fairy tale of, whenever the characters in romance movies are depressed, some funny elements must appear behind. So this is a contradiction, you have to pay attention to it, but you can’t think too much and make the characters heavy. Just It's like letting a balloon float in the air. Whenever there is a wrong idea, the balloon will explode."
