In the movie 28 Days Later (2003), an attractive young man named Jim (Cillian Murphy) awakens from a coma to find himself in a deserted London hospital. Fully nude, he stumbles out onto the street, and discovers that the world has ended. 99% of the population has been transformed into bloodthirsty zombies, who roam the streets, attacking anyone “normal.” Soon Jim teams up with two other survivors, Mark (Noah Huntley) and Selena (Naomie Harris).
The first line of Spiderman (2003) has the narrating Peter Parker (Tobey Maguire) telling us, “Like all good stories, this story is about [a boy and] a girl.”
The beefcake in these movies doesn't make up for the heterosexism. Whether the movie is serious or frivolous, artistic or hack, good or bad, comedy, tragedy, or drama, it must fade out to a man and a woman in love. Even if the “real” plot is about something else, like being bitten by a radioactive spider or saving the world from zombies, there must be a heterosexual romance.
