James Cameron has been developing a sequel to his record-breaking blockbuster Avatar for over 10 years, and it finally hit theaters this weekend. Avatar: The Way of Water is expected to follow in the first film’s footsteps, and box office projections think it’ll make a big splash opening weekend. The critical response has been great so far, with the film earning a certified fresh rating on Rotten Tomatoes and an A CinemaScore. Avatar’s success has a lot to do with the 3D technology instead of the star power, but the film almost cast one of the biggest movie stars on the planet. Matt Damon was almost cast in the lead role but had to pass due to commitments on a Jason Bourne movie, so the role ultimately went to Sam Worthington. Damon has brought up missing out on the part before and now Cameron is telling the actor to “get over it”. During an interview with BBC 1 Radio, the director jokingly claims the actor is still “beating himself up” over not appearing in the biggest film of all time.
