The following films have been nominated for the coveted VFX Oscar: "1917", "Avengers: Endgame", "The Lion King", "Star Wars: Rise of Skywalker" and "The Irishman". The type of VFX differs greatly from film to film: in "The Lion King" it is the photorealistically animated animals shot with simulated cameras by a real DOP, in the Avengers it is the sheer mass of VFX shots (especially the 40-minute final battle with 1,200 VFX scenes).
In Scorsese&s "The Irishman", on the other hand, computer-generated images were used in a more hidden way and were not recognizable as such for many viewers (others, on the other hand, were extremely annoying): the digital rejuvenation by Robert De Niro, Al Pacino and Joe Pesci was fundamentally important for Scorsese&s vision of the mafia story spanning decades. Star Wars" is also featured in the selection for ILM&s innovations in the creation of artificial characters and numerous VFX shots.
In "1917" the VFX were quite traditional, but required a special art to integrate them in a camera shot without (visible) editing.
It will be interesting to see which film the members of the Academy will choose as VFX winner - the technological advances in the realistic animation of animals and the de-Aging of actors are especially trend-setting.
