Australian actor Guy Pearce has filmed a bizarre music video for his new pop single, staging a series of fake infomercials and playing a fitness instructor who grows breasts.

The Memento star, 46, has fulfilled his music dream by recording an album called Broken Bones, and he has released a quirky promo to accompany his new single, Fly All the Way.

Pearce is shown portraying a number of different characters for a series of fake infomercials, and in one he is seen as a cheesy, moustachioed fitness instructor promoting an abs-defining device who ends up growing breasts by the end of the film.

Other characters include a crazy professor with a bad comb-over who promotes a brain expanding pill, a tech guru who has a Usb port installed on one of his fingers, a meat-mad chef, and a wrinkled woman in a purple wig.
