Hauer believed that these poetic lines belonged to his character, who had a sense of poetry and knew what it was. He suggested cutting most of the originally scripted speech and instead came up with the famous ending line, “All those moments will be lost in time, like tears in rain.” Hauer wanted this line to express Roy’s understanding that he has very little time left and to convey how much he cherished life.
“You’re gonna need a bigger boat.” – Jaws
Jaws encountered several production and budgetary difficulties, and one of the most significant problems was the frequent malfunctioning of the mechanical shark. This led to Steven Spielberg having to eliminate the shark from several scenes, which, in turn, caused delays in the characters’ responses to the deadly predator.
According to Carl Gottlieb, one of the screenwriters of Jaws, the iconic line “You’re gonna need a bigger boat” was actually something the crew used to say on set in reference to the producers. Roy Scheider, who played police chief Martin Brody, tried incorporating the line into his dialogue a few times during filming, and it ended up being included in the final cut thanks to the editing of Verna Field. Gottlieb praised the line for being appropriate and realistic in the moment. This came during a time when the production was facing those aforementioned difficulties with budget and issues with the mechanical shark.

The lead character of this war comedy (portrayed by Peter Sellers) cannot conceal his Nazi beliefs, and at the end of “Dr. Strangelove,” he jolts up from his wheelchair and boldly proclaims, “Mein Führer! I can walk!”

Kubrick described his creative method in George Case’s book “Calling Dr. Strangelove: The Anatomy and Influence of the Kubrick Masterpiece.”
According to him, Peter had stated that he was unable to promise to be able to do the same thing twice and that he definitely couldn’t do anything more than two or three times.
On the day that the “Mein Fuhrer” line was coined, Kubrick had six cameras lined up, and no one knew what Peter was going to say or do – not even himself.
“Warriors, come out to play” – The Warriors

Kelly took credit for the bottle idea and how he said the line, but noted that director Walter Hill also contributed to the ad-libbing. While the line was not originally in the script, it was a collaborative effort between Kelly and Hill.
“Funny how?” – Goodfellas
The intense scene in “Goodfellas” between Tommy (played by Joe Pesci) and Henry (Ray Liotta) at the Bamboo Lounge was reportedly based on Pesci’s personal experience.
During the 25th anniversary celebration of “Goodfellas” at the Tribeca Film Festival, Ray Liotta revealed the story behind the famous “Funny how? Funny like I’m a clown, I amuse you?” line.
Liotta shared that Pesci had recounted a time when he worked as a waiter and called someone in the Mafia funny. Scorsese, the director, was intrigued by the story and had them improvise the scene during rehearsals, eventually incorporating it into the film.
