...or can it occur in real life. Because the idea sounds pretty outlandish. The team work required and the risks (20-30 people trapped under a bus) involved would make this a hell of a crazy feat.

There was a case quite some time ago where a bus driving on the road flipped on its side. The passengers got unharmed as the speed was not big,came out and tipepd the bus back on its feet and drove off. there was a news story back then, but that was long ago. so it is possible, though how exactly it is acomplished is unclear. good thing they did was they told them to shoot tires though, as that significantly reduces the suspension ability of this side of the bus thus making it tip much easier. And if it had air lock suspension it could have been locked (disabled) so that would help too. a lot of older buses had those and some still do, its effective way to suspend heavy loads when the need to adjust load is needed in every stop.

Applied Science? All science is applied. Eventually.
me and 1 friend when we were 17 years old (and I wasn't exactly a 'strong' kid) completely lifted the front end of my car off the ground. I'm sure that now(as an adult) I could do it with the same amount of people from the film, with the tires shot out of course, that's a huge part of it.

shareBuses are built with a low centre of gravity for stability. Back of an envelope time - say you've got a bus that weighs 150,000N (about 15 tons) with a cross section that's roughly a 4m x 4m square and the centre of gravity is a metre above the ground. To tip it over you'd use the offside wheels as a fulcrum with the axles, bodywork, etc. as the arm of the lever. Centre of gravity's bearing straight down approximately halfway along the length, so you need to start pushing up with at least half the weight to get the bus moving off the ground, or 75,000N. If an average person can deadlift about 1000N (about 220lbs) if they're going all out, you'd need 75 people to tip the bus off its wheels. Getting it back onto its wheels from tipped should be way easier, as the centre of gravity's now bearing down a quarter of the distance from the fulcrum, with respect to the end of the lever arm (the roof of the bus), so you'd need 37,500N to get it off the ground, or 38 people giving themselves preventable hernias.
Approximations include inelastic square bus, no wheels, etc. so you should rely on my scribbles for absolutely nothing.

When you blow out the tires you move the center of gravity above them aiding in the fulcrum. (But I don't think 9 people could do it.)
