When Romy (Diane Kruger) signs the petition, there is a picture in the bottom left hand corner - a black and white photograph depicting a nuclear mushroom cloud. The award-winning artwork was originally a print advertisement - used to promote the Sony PlayStation 3 (PS3) video game console. The artwork, now often used, but unknown to many is the fact that if you look closely, you will see the shape is of a smiling clown's face appearing in the nuclear mushroom cloud. The clown is none other than the iconic character, 'Sweet Tooth', the psychotic villain of the 'Twisted Metal' franchise. The promotion hinted to the upcoming launch debut of the video game, "Twisted Metal" on the Playstation 3 platform. Although the artwork was created in 2008, the video game itself would not be released until 2012, due to the long development time it took to create.
