Zoolander 2 has some big shoes to fill, and ET is looking at four of the ways the movie could top the original.

1. Returning Favorites: The highly anticipated sequel to Ben Stiller's 2001 cult classic features Stiller and co-star Owen Wilson reprising their roles as over-the-top photogenic male models out to save the world from the villainous Jacobim Mugatu (Will Ferrell).

2. New Additions: While fans are sure to go wild for Stiller's "Blue Steel" modeling poses, new stars Kristen Wiig and Penelope Cruz might steal some of the spotlight. Cruz adds sex appeal as the film's femme fatale while Wiig looks nearly unrecognizable as a fashion mogul.

3. Innovative Promotion: Stiller and Wilson have been all over the world doing big things to stir up excitement for the movie. In January, the actors posed as Derek Zoolander and Hansel in a Valentino store window in Rome, and last year, they walked the runway in character at Paris Fashion Week.

4. Celebrity Cameos: There's supposedly 21 celeb cameos in the comedy with the likes of Justin Bieber, Miley Cyrus and Usher reportedly appearing on screen.
