Here is an image of Skorponok (he's a Transformers movie Transformer, apparently) that I have put up here for safekeeping. It comes from Aint it Cool but they're very good at leaking this stuff just for a few minutes then pulling it down - either because the studio is on their backs or because they're pretending that the studio is on their backs just to make the pulled items seem more exciting and it's all just a big conspiracy...

[EDIT: So, while you're here to look at a Transformer, why not also check out some other stories - the confirmation of Hostel 3, loads and loads of Spider-Man 3 spoilers, the identity of the 13th member of Danny Ocean's gang, a big scoop on the second film in the His Dark Material series, the first image from Frank Miller's work on film of The Spirit... and much, much more. Hope this little lot keeps you busy]
[EDIT AGAIN: An official version of the still has now been released, so here it is below, for contrast-and-compare reasons. Which do you prefer?]
