The Costume: The grizzly version of Academy Award nominated actor Joaquin Phoenix that emerged after he announced he's quitting the business to focus on a rap career, which is the focus of the Casey Affleck mockumentary 'I'm Still Here.'
What You'll Need: The best part of this crazy character is that you can probably assemble most of his wardrobe by fishing through your own closet. It's quite simple really -- all you need is a black suit and tie, a white button-down and a pair of black plastic sunglasses. Or you can pick these things up at most thrift stores.
The real effort will be finding and shaping a wig and fake beard. Oddly enough, there's a whole crop of "biblical beards" that, with a little trimming, could look just like Phoenix's unkempt facial hair. Some even provide a rich head of hair -- perfect for cropping, Phoenix-style.
Accessories: The only extra item you'll want is a microphone. Who can forget Phoenix's unusual performance at the nightclub LIV in Miami, after which he dove into the audience for a post-rap fistfight? If you really want to go the extra mile, have a pal on standby so you can top off your senseless show with a beat-down -- staged, of course.
Lastly, the key to being a convincing Joaquin Phoenix is to walk around in a seemingly drug-induced stupor and have zero interest in anything anybody says to you. If you need a little inspiration just check out Phoenix's appearance on Letterman from back in February of last year.
