It's not just the cars with the curves. With the sort of midriff that could make a blindman choke and a rear end to back it up, Megan Fox is as good a reason as the ludicrously good special effects to go and see Transformers.

She plays Mikaela: a tough girl, a tomboy, a bird that listens to metal and likes to get her hands grubby. She spends the whole film acting competently but totally blindsiding audiences with her fitness.

So yes, the film is amazing: robots, explosions, cars, helicopters, jets and Megan Fox's arse running, jumping, rolling around and getting dirty.

Check out the slideshow below and the vid of her early acting efforts in a bikini. Go see this film.
