John Lennon’s appearance in “Forrest Gump” was achieved through the use of special effects techniques commonly referred to as “digital compositing” or “motion control photography”. This involved combining live-action footage of Tom Hanks, who portrayed Forrest Gump, with a previously recorded footage of John Lennon.

The process of inserting John Lennon into “Forrest Gump” began with the creation of a digital model of the late musician, which was based on existing photographs and videos of him. This digital model was then integrated into the film’s live-action footage using computer-generated imagery (CGI) and motion control photography techniques.

Motion control photography is a process in which a camera is precisely programmed to move in a specific way, allowing for precise duplication of the camera’s movements in post-production. This allowed the filmmakers to place the digital model of John Lennon into the scene, as if he was physically present.

The live-action footage of Tom Hanks was then composited with the digital model of John Lennon, using specialized software. This process involved adjusting the color and lighting of each shot to ensure that the digital model appeared seamless with the live-action footage. In some scenes, the filmmakers also used green screens to replace the background behind John Lennon, adding additional elements to the scene to create a more convincing illusion.

The result was a realistic-looking sequence in which John Lennon appeared to be standing alongside Forrest Gump, as if they were both physically present in the same shot. This illusion was achieved through a combination of sophisticated digital effects and careful attention to detail, making it appear as if the two characters were interacting in real time.

“Forrest Gump” received widespread critical acclaim upon its release in 1994, and is widely regarded as one of the best films of its decade. The innovative use of special effects techniques in the film has been credited with setting a new standard for the integration of digital effects into live-action movies, and has inspired numerous subsequent filmmakers to explore the possibilities of the technology.
