Comedy of Errors
Somewhere halfway the film it struck me: this is a Comedy of Errors. Not literary in a Shakespearian way, far from it.
The title Swerve refers to the story in unintended ways. What comes next? the audience wonders, and indeed, another twist in the plot is introduced in an almost laughable manner. All the clichés are present, including the final shoot out in the train and the girl taking of with the loot, smiling victoriously. As for the barman at the end... he was supposed to be the spider in the web? Goodness gracious, what a moronic twist in the plot.
