10 Most Bad-ass Chainsaw Users In Film

10. Christian Bale - American Psycho

When director Mary Harron's big screen take on Bret Easton Ellis' hugely controversial 1991 novel arrived in 2000, it was a considerable surprise that the end result was not, as anticipated, one of the most horrifically violent films ever made.

Even so, while the adaptation saw fit to expunge much of the book's more excessive cruelty and viscera (partially over concerns that this might overshadow the satirical elements, but surely also because of censorship fears), it still wound up one of the most memorable serial killer movies of the past twenty years.

The enduring cult status of American Psycho is in large part down to the casting of Christian Bale as the titular psychotic American himself, Patrick Bateman. This was Bale's first adult leading role of note, and - as we might now expect from an actor known for his intense method approach - he really goes all out.

And it's never more all-out there than the scene in which a raging Bateman, covered in blood and fully nude except for a pair of immaculately white trainers, chases a prostitute through his apartment complex with a roaring chainsaw in hand. He runs after her into a stairwell where, just as she seems about to escape, he finishes her off by dropping the saw directly onto her head from several storeys up.
