If you want to know when Darth Vader appears on screen, the answer depends on which version of the timeline you’re looking at. This character did not appear in the first movie that everyone remembers. He did not appear in Star Wars (1977). The film was later titled Star Wars Episode IV: A New Hope. Vader’s face remains hidden under a black helmet until later entries.
He steps out more fully in Star Wars: Episode V – The Empire Strikes Back (1980). Here, the mask stays on for most of the runtime. The final film of the original trilogy, Star Wars Episode VI – Return of the Jedi (1983), brings his story to a close to his story. These three films form the core of his appearances.
Fans are often confused about his origins. The prequel trilogy answers how he became the Sith Lord we know. Released between 1999 and 2005 these films focus on the young Anakin Skywalker. The series includes Star Wars Episode I: The Phantom Menace. It continues with Star Wars Episode II – Attack of the Clones. This arc ends with Star Wars: Episode III – Revenge of the Sith.
“The prequel trilogy focuses on the transformation of young Anakin Skywalker into Darth Vader.”
This shift in perspective changes the way we see the villain. We watch him fall rather than just see the result of the fall. The original trilogy shows the consequence. The reason for this has already been presented in the first part. Both are needed for the full picture.
So in which movies does he feature him? The first three are primary sources. The prequels show his history. If you want to see the person behind the mask, start with The Phantom Menace. If you want to see the terror he becomes, head over to “The Empire Strikes Back.”
