Not sure how 'Endgame' ends, haven't read full script: Hulk actor

Mark Ruffalo, who plays the Hulk, has said that he had not read a full script of the movie "Avengers: Endgame" and was unsure how it would end. Meanwhile, Captain Marvel actor Brie Larson called "Endgame" the "most secretive movie possible". Larson said she'd be called to the movie's set without any script for scenes where she had no lines.
