While the answer might be a relatively common one, I believe that Glen Powell is the best up-and-coming movie star in Hollywood. Top Gun: Maverick, Anyone but You, Hit Man, and Twisters are all very different movies that show Powell’s versatility as an actor and ability to get fans to theaters or to show up in streaming. There are other potential movie stars in the making as well, with Sydney Sweeney, Florence Pugh, Jacob Elordi, Paul Mescal, Daisy Edgar-Jones, and more all having great potential, with some making a splash at awards ceremonies or the box office.
