Ben Stiller is detailing the resentment he held toward his father, Jerry Stiller, over how he handled his mom Anne Meara's alcoholism. "When [my mom] was drinking, my dad never really knew how to handle it," Stiller, 59, explains in his new documentary, Stiller & Meara: Nothing Is Lost, which details his parents' love story. "I think he loved her so much and he was so committed to her. Also the act and what they did together was so important, that he had to figure out how to deal with that on his own. But I think I resented him for not acknowledging it to us.
