5. Jacob Black - Twilight (2008)
Summit EntertainmentThere are plenty of unintentionally hilarious moments peppered throughout the interminable Twilight Saga, but few are as downright laughable as the ridiculous wig that Taylor Lautner is forced to wear. Making him look like a baby-faced hobo, the actor was unsurprisingly happy to ditch the shaggy mane for the sequels. The short-haired look is for function as well as fashion apparently, because sporting such a terrible hairdo would result in longer fur when the character transforms into a poorly-realised CGI werewolf, of course. Or it could possibly have something to do with maintaining a respectable appearance when declaring a newborn baby as his soulmate, which isn't creepy in the slightest. Either way, it is a ridiculous-looking wig that has more in common with a washed-up grunge rocker than a smouldering heart-throb.
