Setting the scene
1994 was a landmark film year with Pulp Fiction and The Shawshank Redemption, while digital compositing was new enough to insert actors into archival footage. Winston Groom's novel about a simple man witnessing history was softened for Tom Hanks after John Travolta passed. Robert Zemeckis reunited with Hanks after Forrest's decade-spanning American journey.
What happened
Forrest Gump opened on July 6, 1994, with Hanks as Forrest narrating life from Alabama football to Vietnam to shrimp boats. The film digitally placed him beside presidents and John Lennon, with Gary Sinise as Lieutenant Dan and Robin Wright as Jenny. Alan Silvestri's feather theme and box-of-chocolates philosophy became instant Americana.
Why it still matters
It grossed over $678 million, won six Oscars including Best Picture, and sparked debate about whether it celebrated or mocked American history. The effects house won praise for seamless inserts. Memorable detail: Hanks's ping-pong scenes used a ball added digitally because he could not play at championship speed in real life.
Background
Digital effects placed one character inside decades of archival footage.
