Once Jackie Chan got involved with this movie, it immediately attracted a wide array of talented actors and filmmakers. Executive producer Ira Shuman recalled: "Everyone on the film, actors and crew, wanted to work on a Jackie Chan film. Not only is he a legend, but his good will, generosity, and charm attracted everyone to the project."
The picture's opening montage is made up of several of Jackie Chan's other spy movies, which include Rush Hour (1998), The Tuxedo (2002), Rush Hour 2 (2001), and Operation Candor--original title Fei ying gai wak (1991).
When asked about his favorite scenes in the movie, Jackie Chan mentioned a moment when his character of Bob Ho has a heartfelt talk with his stepdaughter-to-be about her parents' divorce. Chan said: "We get to sit down and talk about ourselves. And it's a very touching scene. I think a lot of families have problems like these today and it's important to explore them in movies."
With this movie, Jackie Chan appreciated the opportunity to try his hand at a family comedy that focuses on his relationship with kids. Chan said: "I really like to make children laugh. I really enjoy hearing from kids that they like my movies."
Jackie Chan adapted his stunts to match the character of Bob Ho. He said: "My character is an ordinary spy. He's not a superhero. I wanted to design the stunts so the audience would believe them." Chan said he continually asked himself during filming, 'Can I do this? Can I do that? Will the audience accept it?'"
