The incredible use of dummies

I like this film as an action/comedy... but...

Did anyone notice the massive use of dummies in this film? The best is at the start when the soldier steps on the landmine when running to the school bus, the other soldier cries "Get down" to Jet Li and we are treated to a blatant shot of what looks like padding stuffed inside clothes, complete with arms stiffly out to the side.

Others include the scene where soldiers entering the hotel trigger the wire detonators and rubber men fly everywhere in the blast. Also when The Doctor is talking to the police on the radio and throws the guy from the window... see how rigidly he falls into the car. Yet again when Jet Li crashes the helicopter into the building, when it explodes you can see several immobile little stickmen scattered around the nearing blastwave. Great stuff... oh how I love dummies!
