An unbelievable amount of effort goes into every moment of a major film production. But the power of a well-timed quote cannot be ovrlooked. From Casablanca to Jaws and Barbie , The Independent looks at 13 of the best examples of improvised dialogue from through the years. Humphrey Bogart improvised this line while playing Rick Blaine in Casablanca.
The story goes that Bogart had begun to use the phrase while teaching Ingrid Bergman, who played Ilsa Lund, how to play poker offset. Then, during the spur of the moment, he slipped it into a reel. This iconic line was delivered by Roy Scheider, playing Martin Brody, when he first sees the huge shark terrorising residents of Amity Island.
The line started as an in-joke behind the camera that Scheider tried to include it at multiple points throughout filming. Eventually, it made the cut during this scene. The boat would move around too much during filming so the team employed the help of a small support vessel to steady it. The boat was, it seems, too small for the job, leading crew members to spout the now-iconic line whenever they saw it.
Rutger Hauer, playing the dying replicant Roy Batty, added this line to the script only hours before getting in front of the camera. The speech was particularly tricky for the team to get right and went through revisions all the way up to filming.
This was a daring move considering Aaron Sorkin, who first conceived the film as a play, is known for being protective of his dialogue. In the screenplay, Nicholson was supposed to say: "You already have the truth" before he revised the line to its more fiery iteration.
