The document discusses how a film represents three social groups: white British people, males, and teenagers. White British people are chosen to subvert the stereotype of them always being villains in action movies. A male character is chosen to challenge the belief that men are always brave by having him be scared. Teenagers are the leads to go against conventions of action movies typically featuring adults. The document argues that while the film changes the stereotype of all men being courageous, it does not portray any social groups negatively or positively, just differently than expected.
