Transformers (2007)

The Girl: Mikaela Banes (Megan Fox)

The Geek: Sam Witwicky (Shia LaBeouf)
 
The Technique: Sam desperately wants to get close to the seemingly unattainable Mikaela, who he thinks only hangs out with jocks.

But just as a happy accident lets him start to get closer to her, fate - and giant f*****g robots - intervene, which helpfully lets Sam play the hero and save the world.

It doesn't hurt that he suddenly has the coolest car in the world. Best hit the local Ferrari dealership, then. Or Cybertron.
