With William Hurt back as General Ross in Captain America: Civil War, it's now being said Betty Ross will be appearing in The Avengers: Infinity War.
According to the UK's The Daily Record, parts of The Avengers: Infinity War will be filmed next month in Glasgow and Edinburgh with "big screen superstars."
The site mentions The Avengers: Infinity War scenes will feature Robert Downey Jr, Samuel L Jackson and Scarlett Johansson.
Further in the report it says the cast for The Avengers: Infinity War includes Liv Tyler, who played Betty Ross in Marvel's 2008 The Incredible Hulk movie.
While the info may be a stretch, it's possible Live Tyler could appear as Betty Ross in The Avengers: Infinity War as the Hulk has been in the worldwide spotlight with both Avengers movies, plus the Hulk goes missing and off to space in Thor Ragnarok. Assuming the Hulk returns from Thor 3, it's possible we could get some sort of Live Tyler Betty Ross and Mark Ruffalo Bruce Banner and/or Hulk reunion scene about not having seen him in a while, missing him, etc.
While The Avengers: Infinity War already has a plethora of characters, I think a Liv Tyler Betty Ross scene with the Hulk would be pretty great. Who knows, maybe it will also set up some sort of future Hulk movie (and no, we don't need her as Red She-Hulk in the MCU).
The Avengers: Infinity War has a May 4, 2018 release starring Josh Brolin as Thanos. Marvel Studios has yet to officially announce the cast, but the following are thought/confirmed to be a part of the movie: Robert Downey Jr., Chris Evans, Chris Hemsworth, Mark Ruffalo, Scarlett Johansson, Jeremy Renner, Cobie Smulders, Samuel L. Jackson, Sebastian Stan, Chris Pratt, Zoe Saldana, Karen Gillan, Dave Bautista, Bradley Cooper, Vin Diesel, Paul Rudd, Elizabeth Olsen, Paul Bettany, Chadwick Boseman, Benedict Cumberbatch, Benedict Wong, Tom Holland and Brie Larson.
