At the time of the filming, Macaulay King had grown up, and the director had to find an actor to play Alex across the United States. Anthony Hopkins , the casting director who found Macaulay King, tested about 2,000 young actors, and finally decided to be played by Alex Linz, who had been shooting commercials. Anthony Hopkins said that when he saw Alex for the first time, he knew that Alex was the protagonist of the film. Alex began acting in commercials at the age of 5, and was familiar to the majority of TV audiences because he played "McDonald's Kids" in McDonald's series of commercials. " Home Alone 3" was Alex's first lead role, but he quickly adapted to the big screen performance. He thinks he is very similar to Alex in the film, and the director agrees with this statement. He regards making movies as a kind of fun, and sometimes makes some interesting suggestions to the director.
"Home Alone 3" moved from a million-dollar mansion in the first film to an ordinary apartment. The film producer and screenwriter John Hughes pointed out that although the film still uses home as the theme, it is by no means "Home Alone 1, 2" of. This time, the wise and brave Super Imp has two more assistants: a pet mouse and a rappy parrot. The viewability of "Home Alone 3" is better than that of the first and second parts.
