The Guardian Unlimited has a slightly amusing article in relation to the teaser trailer for 'Goblet of Fire' that has just been released.
"The boys are now sporting Beatles haircuts: Harry (Daniel Radcliffe) especially looks like a young George Harrison, while Ron (Rupert Grint) comes across more like a ginger Kurt Cobain, only cleaner. Meanwhile, Hermione (Emma Watson) is turning into a prom queen."
"And bizarrely, Dumbledore (Sir Michael Gambon) is wearing his beard as a ponytail."
Empire also has a piece which is just as funny.
"Whatever's going on, it clearly takes up time that would otherwise be spent at the barbershop, since both Ron and Harry have considerably shaggier hair."
"However, we also get our first glimpses of the Tri-Wizard tournament that proves Harry's biggest challenge in the film, as three schools of wizardry compete for what is essentially the Oxbridge Boat Race of Wizarding schools."
"In particular, we see Harry tackle a fire-breathing dragon and the dangerous Mer-people, while Hermione looks on and shrieks."
