Tropic Thunder's protagonist, Tugg Speedman (Ben Stiller), is a faded action star struggling to come to terms with his declining masculinity. His character, along with his co-stars Les Grossman (Robert Downey Jr.) and Jeff Portnoy (Jack Black), embodies a hyper-masculine ideal that is both ridiculous and fragile. The film's portrayal of these characters' egos, insecurities, and desperate attempts to reclaim their masculinity serves as a commentary on the societal expectations placed on men.
