10 Movie Heroes Who Won By Dumb Luck
3. Tucker & Dale - Tucker & Dale Vs. Evil
Tucker and Dale vs. Evil is a film centered entirely around an hilarious spate of accidents and misunderstandings, as well-intentioned hillbillies Tucker (Alan Tudyk) and Dale (Tyler Labine) are mistaken for a pair of murders by a group of college students.
Through a series of unfortunate circumstances, the college students start getting themselves killed in various ridiculous ways as they flee the pair in a panic, no matter that there is in fact a real killer in their midst.
Eventually it's revealed that the real psycho is one of the students, Chad (Jesse Moss), and when he plots to kill his friend Allison (Katrina Bowden), Dale foils him by throwing a box of chamomile tea at him, causing him to have an asthma attack and fall out of a window.
Though Chad ultimately survives the fall, Tucker and Dale still managed to temporarily foil him, save Allison, and get to safety through the random fortune of an allergic reaction, in turn leading to Dale and Allison beginning a relationship.
