“Zoolander” is a hilarious 2001 action/comedy starring Ben Stiller as an aging male supermodel named Derek Zoolander. In the film, he has to compete against a fierce up-and-comer, Hansel, played by Owen Wilson.
As the competition comes to a head, David Bowie makes an appearance as himself to judge an intense runway walk-off. Ben Stiller later Tweeted that he “can’t believe David Bowie actually did this. We were all in shock.”
Cate Blanchett: Hot Fuzz
If you have a crush on Cate Blanchett and you’re wondering how you missed her in "Hot Fuzz," here’s why. It’s because she was covered head to toe in surgical gear. The cameo came about when director Edgar Wright learned about the actresses’ love of "Shaun of the Dead."
He extended an offer for her to appear in his new film in 2007. More than years later, she's become an even bigger success (she was pretty big then) and has starred in some major blockbusters like "Ocean's 8" and "Thor: Ragnarok."
Luke Hemsworth: Thor: Ragnarok
Several actors made a surprise cameo in this Marvel superhero film. In fact, the movie was full of them. The protagonist, Thor, played by Chris Hemsworth, has a fake version of himself within the film as well.
In the play, Thor’s role is filled by the actor’s older brother, Luke Hemsworth. The franchise is known for its humor, and that scene with the play, “The Tragedy of Loki,” in particular, is filled with celebrity cameos.
Lady Gaga: The Sopranos
Long before Lady Gaga was a household name and a Grammy award-winning artist, she was a teenager just trying to get her foot in the door of the entertainment industry. And, in 2001, she did just that when she briefly appeared in an episode of the hit HBO show, "The Sopranos." On the show, she plays a rebellious teenager at AJ’s school.
Seven years later, she released her hit debut song, Just Dance. Afterward, Gaga proved that she had major acting skills of her own by starring in the award-winning "A Star is Born."
Bill Murray: Zombieland
A-list funnyman Bill Murray makes us laugh as usual with his pop-up appearance in this comedy film. In "Zombieland," he plays himself – although potentially the undead version, or so he’d like us to think. His cameo was such a hit they invited him back for the second installment in the series.
Unfortunately, his cameo in “Double Tap” involves his death, so if he comes back again, it will be in full zombie mode. The Golden Globe-winning actor is keeping busy and has several projects coming up soon.
