There are a lot of films that I'm excited to watch this year, but these are the only ones that will probably make me go watch them in the cinema.
Alien: Covenant - I'm a fan of the Alien franchise, liked Prometheus as well so I'm naturally excited about the next film that is hopefully going back to it's roots. Dunkirk - The Battle of Dunkirk directed by Nolan who has never made a bad movie? Oh yes, please. T2: Trainspotting - Boyle coming back to direct a sequel to the brilliant Trainspotting with the same cast. Even though it's another sequel made after 20 years I have hopes for this one to be good. Love McGregor and judging by the official trailer it's looking good. King Arthur: Legend of the Sword - I'm a huge fan of Guy Ritchies comedic style of direction and the trailer for this one excited me as well, but it could honestly be really amazing or really shit. I don't know how Ritchies style could translate to a fantasy setting, but I'm still excited for the film.
Star Wars: The Last Jedi - It's Star Wars, I don't need much else to get excited. The chance to hear another new story from the universe I love is enough to get me excited.
