i have to say my favourite big name actor must be Michael Douglas as Hank Pym in the Ant-Man films
i also never thought he would say yes to these kind of films
and how perfect Benedict Cumberbatch is as Doctor Strange, like i don't think anyone would slay that role better than him
and a honourable shout out to the recently passed away LEGEND that was Robert Redford, also a decent small role from him in Avengers films: Captain America: The Winter Soldier and Avengers: Endgame
