Anthony Michael Hall, a prominent figure in the Brat Pack era, declined to participate in Andrew McCarthy's documentary 'Brats' due to his focus on new projects and moving forward. While some members like Rob Lowe expressed discomfort with the Brat Pack label, Hall remains indifferent, embracing his past with John Hughes. The documentary reunites iconic '80s stars to discuss the impact of the New York Magazine article that coined the term. Despite Hall's absence in the film, he continues to celebrate his Brat Pack legacy and pursue diverse acting projects.
