One of the most memorable scenes in the film features the Kraken attacking the Flying Dutchman. To capture this sequence, the filmmakers used a combination of practical and visual effects. A large, remote-controlled model of the Dutchman was built, and the actors performed on a specially designed set that could be easily destroyed to simulate the attack.

During pre-production, the filmmakers faced a significant challenge: creating a believable and terrifying sea monster, the Kraken. The visual effects team, led by John Knoll and Hal Hickel, worked tirelessly to design and animate the massive creature. The Kraken's design was inspired by various sea creatures, including the giant squid and the octopus.

Filming the Kraken scenes was a complex and challenging process. The visual effects team used a combination of motion capture, CGI, and practical effects to bring the creature to life. The actors had to perform in front of a green screen, reacting to a digital representation of the Kraken that would be added later in post-production.

The special effects in were a major highlight of the film. The visual effects team, led by Industrial Light & Magic (ILM), created stunning CGI environments, characters, and sequences that transported audiences to a fantastical world.
