You were my brother, Anakin is a memorable quote from Star Wars: Episode III – Revenge of the Sith.
It is a popular meme format, with image macros and photoshop edits featuring screenshots of the scene.
Star Wars: Episode III – Revenge of the Sith was premiered in the United States on May 12th, 2005.
The final scenes of the motion picture depict Obi-Wan facing off Anakin (played by Ewan McGregor and Hayden Christensen respectively) on the planet Mustafar.
Obi-Wan says the phrase from the high ground, as Anakin is chilling on the banks of a lava river.
The phrase started to be featured in image macros and memes in 2012, becoming more popular with the rise of Prequel Memes.
It would become a popular format on the r/PrequelMemes subreddit, which was created in December, 2016.
