Is that Hansel? Nope, it's Billy Zane!
The video starts off by showing the back of Hansel (played by Owen Wilson) reading a newspaper by a fountain. Stiller asks, "Hey Hansel, wouldn't it be cool if Billy Zane was in Zoolander 2?" But as the camera zooms in to reveal the figure's face, viewers find that the blond-haired Hansel was actually Zane in disguise!
"Yeah, that'd be great," the 49-year-old Titanic actor says coolly.
"Whoa," Stiller says in response to the big reveal.
And "whoa" is right! Zane joins the film's original cast members which include Stiller, Wilson and Will Ferrell.
Just last month, Stiller and Wilson strutted down the Valentino runway as Derek Zoolander and Hansel to announce the second installment of their iconic comedy film. Since then, Stiller's Instagram has been the source of casting confirmations for the new movie set to release in February 2016.
Other confirmed cast members revealed by the comedian's Instagram include Penélope Cruz and Stiller's on-screen son, Cyrus Arnold. Bridesmaids star Kristen Wiig will also have a role in the upcoming sequel.
We can't wait to see what other surprises the star has in store for us!
