Independence Day (1996)

This was a completely genuine reaction on Smith’s part.

Thanks to the talents of Will Smith and Jeff Goldblum,Independence Daywas able to be a perfect summer blockbuster based on a simple alien invasion premise with some comedic undertones. Writer and producer Dean Devlin credits much of what is seen in the final movie to improvisation (vialooper.com). DespiteIndependence Daygenerally not being considered a comedy,its most famous improvised moment is Smith’s hilarious line"And what the hell is that smell?“as he drags the body of an alien across the Utah salt flats.

7"I’m Walking Here!” — Ratso Rizzo

Midnight Cowboy (1969)

As a con-man duo movie starring two actors on their way to becoming legends in the business,it makes sense thatMidnight Cowboywould work best with some improvisation,allowing for natural interactions. However, the movie’s most famous moment surrounds Dustin Hoffman’s Ratso. It has been debated over the years whether this scene was improvised, butJon Voight’s recent explanation of Hoffman’s iconicMidnight Cowboymoment is in favor of him coming up with it on the spot.

According to Voight, the production crew was supposed to be blocking off cabs while they were filming in the middle of a busy New York City street. At one point, a cab driver got tired of waiting and sped through the shot, prompting Hoffman’s"I’m walking here!“In his interview withJake’s Takes, Voight said:

“[…] and he says this line, ‘That’s a good way to get insurance, you know,’ whatever it was, and I knew he had that line stored up in him to say somewhere in the film and the thing that just happened, he did that instinctually […]”

Therefore, Voight credits Hoffman with some forethought, suggesting another process of improvisation and creating organic character moments.Hoffman might have had some ideas in his head of things it would be great for his character to sayand brought one of them out at the perfect time to create an immediately amazing scene.

Iron Man

Iron Man is the first film in the long-running Marvel Cinematic Universe franchise. Robert Downey Jr. stars as Tony Stark, who becomes Iron Man after he is kidnapped and discovers terrorists are using weapons developed by Stark Industries. Gwyneth Paltrow stars as Tony’s love interest Pepper Potts alongside Jon Favreau as Happy Hogan and Jeff Bridges as the villainous Obadiah Stane.

Downey adding this line at the last minute changed the trajectory of superhero pop culture, with secret identities and double lives becoming less frequent,as most of the MCU heroes are publicly known by their real names. It also became a recurring motif with the franchise’s original hero; Tony always goes back to the absolute truth about who he is, how he has changed, and what he must do. This moment that wasn’t even in the script forIron Manbecame one of the most amazing scenes ofAvengers: Endgame, tying the whole story together.

20 Best Godfather Quotes From The Whole Trilogy

The best Godfather quotes are some of the most famous lines in all of movie history. This is a list that you can’t refuse.

Before going out to kill a traitor bodyguard, Clemenza’s wife reminds him to pick up cannoli. After Paulie is dead,Clemenza tells Rocco to"leave the gun, take the cannoli,“not forgetting his errand for his wife despite the murder,because it is a simple fact of his life. Richard Castellano’s real wife Ardell Sheridan plays Clemenza’s wife, and she suggested adding the"take the cannoli"part of the line to riff off her comment (viaThe Hollywood Reporter). Castellano reportedly did not return forThe Godfather Part IIwhen his condition of Sheridan writing all his lines was rejected.

1"I Know.” – Han Solo

Star Wars: The Empire Strikes Back (1980)

George Lucas might not have yet known that Luke and Leia were going to be siblings at the time of the production ofThe Empire Strikes Back, but the movie still puts a lot more emphasis onHan and Leiaas the couple to be rooting for.It has become an urban legend that Harrison Ford improvised one of their biggest moments,which isn’t entirely true (viaCBR). For the scene of Han being frozen, the script originally had Leia saying,“I love you. I couldn’t tell you before, but it’s true,”and Han replies,“Just remember that, ‘cause I’ll be back.”

Star Wars: Episode V - The Empire Strikes Back

The Empire Strikes Back is the second installment in the original Star Wars trilogy, directed by Irvin Kershner. Released in 1980, it follows Luke Skywalker as he trains under Jedi Master Yoda, while Princess Leia, Han Solo, and the Rebel Alliance face ongoing threats from the Galactic Empire and Darth Vader.

In reality, Ford suggested the line while workshopping the script with director Irvin Kershner before filming. This was lucky forStar Wars, asthis line quickly became one of the franchise’s most iconic moments and solidified Han and Leia’s dynamicof their love for each other despite arrogance and stubbornness. A certain amount of flexibility is always good for filming, allowing several instantly beloved movie moments to see the light of day.
