I'm looking for a short clip to show my class for a lecture on teamwork, unit cohesion and esprit de corps. Am sick of them being a bunch of whiny snitches, who'd happily stab their classmates in the back if they thought they'd get a merit award out of it. They're Year 9s, i.e. around 13 yrs old, so anything with swearing is out and that pretty much gets rid of anything decent after the 1960s. I'd originally thought about the scene from The Dirty Dozen where they all 'down tools' and refuse to shave with cold water and start bonding as a group, but I don't know if it's really what I'm looking for. Ideally around 5-7min long to fit in morning registration. Anyone know of something appropriate?
