The Moment: Sylvester Stallone returns to play the character he so successfully retired in 2006's Rocky Balboa, this time in the role of the trainer as Apollo Creed's son Adonis (Michael B. Jordan) seeks to become the champ himself. Rocky will meanwhile battle his own (unspecified) demons outside of the ring. Why It Will Define 2015: Because there are few cinematic characters as iconic as Stallone's Rocky, and even though it felt like the character's story was totally sewn up in his last movie, this will give fans one (hopefully) final glimpse at the aging icon. Hopefully, though, it won't give him as depressing a final send-off as Rocky V did, and still manage to conclude his story on a somewhat optimistic note.
