It's not exaggerating to say that Avengers: Infinity War is going to be the biggest Marvel movie yet, if not one of the biggest Hollywood blockbusters in general. Not only will Thanos finally be wreaking havoc after being teased as a threat since 2012's The Avengers, but the movie is including nearly every major Marvel hero introduced over the Marvel Cinematic Universe's lifetime. However, it's not just the heroes who will be brought into the action. Several of the heroes' allies have been confirmed to return, and now there's word that supporting Hulk character Betty Ross will finally be brought back in this epic tale.
In their report about Avengers: Infinity War supposedly shooting in Scotland, Telegraph mentioned that Liv Tyler is rumored reprise her role as Betty Ross, gamma scientist and Bruce Banner's ex-girlfriend. Ross' sole appearance in the MCU was in 2008's The Incredible Hulk, and she hasn't been mentioned in the nine years since then. While Bruce Banner/Hulk has long been confirmed to appear in Avengers: Infinity War, this is the first mention of anyone from his supporting cast being featured in the third Avengers flick. There's no word yet on if Betty's father, General Thaddeus "Thunderbolt" Ross, will also return.
Betty Ross has been one of the Hulk key supporting characters since the Green (well, gray at first) Goliath's comic book debut, so it was only appropriate that she was included in The Incredible Hulk, the second MCU film out of the gate. In this continuity, Betty helped Bruce Banner with the Gamma Pulse experiment, which was part of the Bio-Tech Force Enhancement Project, an attempt to recreate the Super-Soldier Serum. Unlike her father, Betty continued to believe in Bruce after he became a fugitive, and after he came back into her life years later, she helped him stay hidden from the U.S. military and track down Samuel Sterns. Following the battle with Abomination, Bruce went on the run again, and the last shot of Betty was her reminiscing on her brief reunion with him.
Due to entanglements with Universal over distribution rights, The Hulk hasn't been given another solo movie since The Incredible Hulk, instead being a major player in the Avengers adventures and the upcoming Thor: Ragnarok. Although Thaddeus Ross' inclusion in Captain America: Civil War served as a reminder that Hulk's supporting cast is still around in this universe, Betty's return is long overdue. Since things didn't work out romantically with Black Widow in Avengers: Age of Ultron, maybe Bruce will be able to rekindle the spark with Betty in Avengers: Infinity War in the midst of the insanity with Thanos and the Infinity Stones.
Avengers: Infinity War will be released in theaters on May 4, 2018, and Avengers 4, which will be shot during the same production cycle, will arrive on May 3, 2019.
