Generally blockbuster movies are left hush-hush until the opening. Even then, people refuse to get on social media to avoid any spoilers. Google and Twitter have both leaked a big spoiler for the new Infinity Wars movie, also known as Avengers: Endgame.
In a tweet posted earlier this month, actor Ryan Reynolds seems to elude to his character "Deadpool" being in the new movie. Knowing that Reynolds likes to play pranks, people started looking into the validity of the statement. Low and behold, Google presents the same cast, with Reynolds appearing in the cast as "Deadpool."
