10 Off-Screen MCU Moments EVERYONE Wanted To See
6. Young Thanos Speaks To Titan's Council - Avengers: Infinity War
In Infinity War, Thanos explains to Doctor Strange (Benedict Cumberbatch) that his plan to wipe out half of all life in the universe was a result of watching his own birth planet, Titan, be ravaged by over-population.
He offered a solution to the council of Titan, to kill half the planet's population in order to free the rest, but was dubbed a madman, no matter that it then happened just as he said it would.
Though we never actually see this scene play out, the Russos and co. did originally plan to include a scene of young Thanos talking to the Titan council in Endgame, yet ultimately scrapped it for the sake of redundancy.
Still, given how little concrete information we have of Thanos' backstory, it sure would've been fascinating to see him as a younger man, lending further context to how he became the totalitarian tyrant we knew him as.
