Star Trek vs Star Wars (2021 space-opera film)

Star Trek vs. Star Wars would be a 2021 American action-adventure space-opera film and crossover between the Star Wars and Star Trek franchises. The film would be directed by James Cameron and written by Stephen Spielberg and would star Chris Pine as James T. Kirk, Zachary Quinto as Spock, John Cho as Hikaru Sulu, and Zoe Saldana as Nyota Uhura. The plot of the film revolves around the Enterprise being inexplicably transported to the Star Wars universe after a warp drive malfunction, and they soon find themselves fighting a war against the Galactic Empire while trying to reach their own universe. The film itself would be entirely noncanonical to either setting, and any established lore is also noncanonical.
