Liv Tyler is Betty Ross
Fun fact: Betty's life sucks. After dealing with a controlling general for a dad and falling in love with Bruce Banner who becomes the Hulk, she herself is subjected to Gamma radiation and becomes the villain Harpy. She eventually reverts back to good old Betty but later dies when she is poisoned with Abomination's blood. Her daddy then became the Red Hulk and resurrects her into Red She-Hulk. What a ride.
