Jake Gyllenhaal is the eponymous teenager who just doesn't really fit in. Ever since he was a young child, he has struggled and it's only "Gretchen" (Jena Malone) who has anything to do with him. It's maybe on the psychiatrists couch that he seems most able to relax - under hypnosis - and under that influence we embark on quite a curious learning curve that follows "Donnie" from childhood through the turbulence of his adolescence. Now his development might not have been helped by the arrival of an aircraft engine through his roof, so his body's self defence mechanisms seem to be seeking solace from his friend "Frank". No, he's not real - well not unless life-sized bunnies have escaped up the looking glass, and when he is told that the world will end in just short of one month's time, then it's time to find his psychological TARDIS - or as near as he can. Why did he survive the accident? Well that's the question that continues to plague him as his torments mount and his frustrations begin to manifest themselves in petty criminality and a testing of his relationship with his only real friend "Gretchen". Now I don't know about you, but until now I'd never thought of bunny rabbits as being the least menacing. Think "Thumper" from "Bambi" (1942) and that's about it. Here, though, auteur Richard Kelly uses the light - well mostly the dark - to create quite a sense of peril as young "Donnie" seems to lose what little grasp of the plot he ever had. It's also quite darkly comical at times, with the rather potent script treading a line between fact and fiction in an engagingly blurred fashion. Gyllenhaal plays the part well, adding a vulnerability to a role that is quite difficult to define and as we progress, well some of our earlier assumptions become just a little more fluid. The haunting Gary Jules version of the Tears For Fears "Mad World" song tops a strong 1980s soundtrack and the whole film has an ethereal eeriness to it that I did quite enjoy.
