Surprise! You weren't expecting these actors to show up in other movies. See the top 10 here. Spoilers. Spoilers. Spoilers.

10. Dodgeball: A True Underdog Story - "Judge's Decision" - Chuck Norris

The best deciding vote in movie history is done by one of the all time best. It's the best non-round-house-kick moment Chuck Norris has had on screen.

 

9. Eurotrip - "Scotty Doesn't Know" - Matt Damon (NSFW Sexual Language)

I wonder how many people in the theater first saw the stage and said, "Is that Matt Damon? It is Matt Damon!" Oh Scotty. What a horrible way to find out that his girlfriend has been cheating on him. He hears this song all over.

 

8. Anchorman: The Legend of Ron Burgundy - "The Back Ally Brawl" - Luke Wilson, Tim Robbins, and Ben Stiller

After Old School was so popular, a movie with both Will Ferrell and Vince Vaughn wouldn't be complete without Luke Wilson. Well this movie didn't disappoint with a barrage of cameos in one epic scene.

 

7. Austin Powers in Goldmember - "Austinpussy" - Tom Cruise, Gwyneth Paltrow, Kevin Spacey, Danny DeVito, and Stephen Spielberg (NSFW- Language)

The opening to Austin Powers in Goldmember was a spy movie all of it's own. It had people in the theaters really happy to see a bunch of A-list celebrities take on the different characters in the Austin Powers universe. The scene stealer is Danny DeVito taking on the role of the late Verne Troyer.

 

6. Hot Shots Part Deux - "I loved you in Wall Street" - Martin Sheen

This is one of the funniest cameos of all time! Here you have Topper (Charlie Sheen) getting his voice-over interrupted by Captain Benjamin L. Willard (Martin Sheen's character in Apocalypse Now) and then they acknowledge how much they loved each other in Wall Street. The father and son point and thumbs up just make this cameo that much better. So funny!

 

5. Wayne's World 2 - "The Partial Ocular Albino" - Kevin Pollak 

I was up in the air between this cameo and the cameo made by Charlton Heston later in the movie. The reason that his one wins out is because that "lower case j's" line made me laugh so hard when I first saw it. I was not expecting that line at all. Loved it!

 

4. Zoolander - "But why male models" - David Duchovny

What makes this cameo/scene is so great is the fact that Ben Stiller screwed up. He had already asked "why male models" earlier so when he screwed up and repeated the line, Duchovny just rolled with it and said he already told him. It was perfect for the movie and tied in really well. ***Bonus Cameo*** the photographer of the photo shoot is Patton Oswalt.

 

3. Happy Gilmore - "The Price is Wrong B***H!" - Bob Barker

Bob Barker orginially said no to being in Happy Gilmore but when he found out that he was going to win the fight, he said yes. Also, they were going to use a stunt double for Barker until he told the director that he knows how to fight. Barker has spent years studying Tang Soo Do Karate under the above Chuck Norris.

 

2. Zombieland - "BILL F*****G MURRAY" - Bill Murray (NSFW-Language obviously)

After anyone saw Zombieland, the overall consensus was that it was a good movie but the cameo is one of the best of all time. Bill Murray as Bill Murray doing the most Bill Murray thing ever of pretending to be a zombie so he can go play golf. It's so great! Woody Harrelson is really great in this scene as he is star struck by one of the funniest people of all time. It doubles the funny considering these two were in Kingpin together.

 

1. A Million Ways to Die in the West - "Great Scott" - Doc Brown - Christopher Lloyd

This is my favorite cameo of all time. I already really liked A Million Ways to Die in the West but the fact it's set during 1885 when Doc Brown goes back in time after being struck by lightening was such a genius touch by Seth MacFarlane. What a nod to one of the greatest franchises in cinema history. This cameo made me so happy when I saw it. Like the Hot Shots cameo, it's great when a movie acknowledges another movie like this one does. He's even working on the DeLorean. Excellent!
