You would have thought, given his recent career choices and predilection for high-profile turkeys, that dentistry in his film posters would be the least of Jack Black's concerns. If he's happy to star in an ill-conceived modern adaptation of Gulliver's Travels, you have to suspect that his attention to the finer details of film marketing isn't exactly primed, but even he must have had some trouble with the decision to remove all of his teeth for this poster. Clearly in order to stop him from looking like he was manically grinning, the offending Photoshopper here clearly decided that toothless was a better emotion than anger mixed with fear (which would have been the completely harmless effect achieved by actually retaining his chompers.) It's also unnervingly hard to shake the feeling that Black is some sort of giant life-like sex-doll with added BDSM accessories, which might have actually made Gulliver's Travels a little easier to stomach.
