Never one to be outdone by a half-naked Alexa Vega in her new, revealing outfit for Machete Kills, David Arquette (Scream) recently tweeted a three-quarters-naked picture of himself from the post-apocalyptic picture, Orion.  Directed by Asiel Norton (Redland), Orion centers on a savage hunter (Arquette) who searches for his missing brother in a post-apocalyptic wasteland devoid of infrastructure.  The picture, currently filming in Detroit, also stars Lily Cole (Snow White and the Huntsman) and Goran Kostic (Taken).  Hit the jump to see the pictures.
