The Man From U.N.C.L.E was a famous spy show in the 60ties. There was a movie in 1983 and another in 2015. The first movie had a special guest: the shape-shifting agent James Bond. He was in the form of George Lazenby who, unfortunately, is considered the worst of Bonds.

The Last Action Hero featured a mix between reality and world of movies. In this movie Schwarzenegger plays both a fictional cop and himself separately and Sly was the Terminator. When Arnie goes to his precinct you can see Catherine Tramell outside in the same clothes she gave the "show" during an interview. Speaking of Terminator, you can also see there the star of the next cameo...

... T-1000. You can also see the murderous robot in Wayne's World when he asks Wayne did he see a particular boy. And to think Myers didn't like that scene.

Benjamin Willard was a character from Apocalypse Now that had a bad time in Vietnam. Fourteen years later Martin Sheen reprises the role in Hot Shots 2; He also yells at his son's character "I loved you in Wall Street", talking about complicated jokes.

Ray Stantz is a beloved character from the original (and for many the only) Ghostbusters. If you want to know what happened to his after the events of the movie, Casper from 1995 gives you the answer- he still fights ghost and is still hilarious.

Matt Hooper from Jaws. Richard Dreyfuss hated working on Jaws so much he refused to come back for the second part. It took him years to agree to play Matt again, this time he is hiding from sharks under a false name Boyd but is found by piranhas in Piranha 3D.

John McClane in Loaded Weapon. This spoof was made when spoofs were funny and not just remakes of real movies scene by scene with amateur actors hoping for cheap laughs. Emilio Esteves plays the parody of Lethal Weapon's Mel Gibson. He also lives in a trailer on the beach, but when the bad guys shoot his home up they find out it was the wrong address and they destroyed McClane's trailer by mistake.

If you remember the first Alien you might remember there was only one alien on Nostromo and it didn't die from a sneeze. The way alien was hatched wasn't particularly pleasant for John Hurt's character. Spaceballs in 1987 once again had an alien burst from his chest with him saying "Not again".

A Million Ways To Die In The West is a movie made by Seth MacFarlane in which he also plays the main hero. When Seth is riding his horse he sees something suspicious... and it turns out to be Doc Brown (you know Back to the Future) working on his time machine.

Bonus. In the movie Maverick made by Richard Donner, the guy that made Lethal Weapon, Mel Gibson's character gets robbed by a crook played by... Danny Glover. Maverick finds the robber familiar, Lethal Weapon music starts to play and Gibson and Glover try to remember where do they know each other from. Great stuff.
