Trivia

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).

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."

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?'"
