Why Rocky Could Be the Best Sci-Fi Movie Alien in YearsMeet Rocky! Like Ryland, Rocky is alone and has journeyed to the star Tau Ceti to figure out why this star, of all the nearby stars, is unaffected by Astrophage.

Will Project Hail Mary go down as one of the best alien-makes-friends-with-a-human movies of all time? Project Hail Mary hits theaters on March 20.
