Continue to check back with us as we will be adding more information as it becomes available.Arguably 2026's first truly great film by popular consensus was Christopher Miller and Phil Lord's acclaimed adaptation of Project Hail Mary. Starring Ryan Gosling in the role of a middle school teacher turned unlikely astronaut charged with saving humanity, Ryland Grace, the blockbuster earned rave reviews upon blasting off back in March, earning early buzz as a potential Oscar contender. Now that the year is winding down, it's still considered one of the finest adventures to hit the big screen this year and certainly among the best sci-fi movies, full of heart, high stakes, a bit of humor, and one very lovable alien named Rocky. Yet, the end of the year is bound to give it a run for its money, with two sci-fi titans set to close out 2026 on a thundering note — Dune: Part Three and the MCU's next big crossover, Avengers: Doomsday. One Project Hail Mary star has, fittingly, joined the MCU this year, with Gosling's casting as Ghost Rider during San Diego Comic-Con. Now, another member of the international task force that launched him into space is following him and she'll appear even sooner than the Spirit of Vengeance's 2028 release date. The Hollywood Reporter has officially confirmed that Oscar nominee Sandra Hüller will appear in Doomsday. Marvel has not commented yet, but she's said to have a cameo role as part of the star-studded roster led by Robert Downey Jr.'s Doctor Doom.
