Justice League: Crisis on Infinite Earths (film)

Justice League: Crisis on Infinite Earths is an imagined film that takes place in the DC Cinematic Universe. It is the sequel to Justice League: Crisis on Two Earths and serves as the penultimate film in the entire DCCU. This film is the eighth film in the Justice League film series and the second in the "Crisis" trilogy. It is the only film to cross over into other DC franchises, such as the Arrowverse. It is the most ambitious and expensive film of all-time. A 4.5-hour ultimate edition is released on a streaming service. It is based on the Crisis on Infinite Earths and Infinite Crisis comic book storylines and includes the largest cast ever assembled.

Plot

 * The Anti-Monitor, who originated from the antimatter universe, has been destroying Earths due to an unknown catalytic event. As it is destroying Earth-17, it comes to a head with The Monitor, aided by the Phantom Stranger, who is the only being to coexist in different universes and has the ability to transfer between them. The Anti-Monitor destroys the Monitor, with the Phantom Stranger barely escaping before the universe is destroyed. The Monitor tells Phantom Stranger but he died to recruit heroes and villains from the remaining Earths together for a strong defensive. The Monitor dies, and his energy is released to align the remaining dozens of Earths in a formation to potentially merge. An injured Phantom Stranger uses his last ability to transfer to Earth-1.
