For his small role in Fox Searchlight's Wild, Greg never officially met Academy Award-winning actress Reese Witherspoon before jumping right into improvising their scenes. For their "sex" scene, where they were supposed to be strangers in the film, they were even more strangers in real life, barely sharing a single word off-screen. The sensitive nude scene was performed on a "closed" set with only the director Jean-Marc Vallee (also shooting hand-held while barking direction), a boom operator, and the two actors. Never having had engaged in such a scene himself either, Greg did not know what a "cock-sock" was (the thing which covers the naughty bits) and had to be told by the Wardrobe gal on what it was for and how to put it on. And although they shot an entire "pick-up" scene in the bar complete with significant dialogue, it was unfortunately yet appropriately cut from the final print of the film, of which he appears in short flashes with Reese throughout.
