3. 'He’s Alive…and in Perfect Hibernation' ('The Empire Strikes Back')
The scene raised the stakes for the entire story: Han Solo was frozen in carbonite, meaning one of the saga's major heroes was taken out of commission, his ultimate fate left uncertain. The sequence is filled with dread, anguish and grief, making our characters feel like real human beings (no offense, Chewbacca; we feel your pain, too) for perhaps the first time in the entire saga. Han's parting line to Leia's "I love you" (“I know") is as perfect as it gets.
