Betty Ross is finally coming back to the MCU, and her life must have changed significantly since The Incredible Hulk. It was recently confirmed that Liv Tyler is returning in Captain America: New World Order, which is scheduled to debut in theaters on May 3rd, 2024,16 years after Tyler's last (and only) outing as Ross. The film’s relative quality, lack of a sequel, rights issues with Universal, and subsequent recasting of Mark Ruffalo over Edward Norton all doomed The Incredible Hulk’s standing in the franchise. Thankfully, however, it seems that the movie will finally enjoy more ties to the MCU.
