9. Ben Stiller Dodgeball
I realise that Dodgeball is a comedy so overacting is sort of the whole deal here, but sometimes a performance stands out in the annals as something so profoundly ridiculous you just have to stand up and applaud. So without further ado, I give you Dwight Goodman. Its literally a perfect performance from Stiller, whos clearly having a whale of a time portraying an egotistical idiot, and utterly hilarious to boot. He has to work hard to take this movie from under the nose of Rip Torn as Patches OHoulihan who offers him stern competition in the overacting buffoonery stakes, but theres just something awesome about the part of Dwight Goodman, and hes eminently watchable in all he does. Whether hes puffing up his inflatable crotch, flipping the bird from the back of camp scooter or absolutely massacring Spanish, theres an over-the-top energy to him which is just phenomenal. After all, nobody makes him bleed his own blood. Its a shame that Dodogeball is now likely to be remembered as the film which carries that now-heroically awkward cameo from Lance Armstrong, because it deserves to be remembered for Stillers anarchic performance. Him shoving pizza down his shorts for some sort of gratification is something that has to be seen to be believed, and he brings a manic-ness to proceedings which is badly needed next to Vince Vaughns slacker-straight man persona. Honestly though, its the moustache that does it for me. Its like a tiny rodent just took up residence on his top lip, and the man just rolled with it. Couple that with the Globo Gym cobra dance and youve got an overacting comedy winner.
