Well I haven't seen jackie chan's my story but the teeth are kept closed and are clenched with each strike. This reduces the rebound that happens when bak mei fundermentals are used to strike with ging. Else you can give yourself a headache and not all of your power is going into the person being struck. Bak Mei power is sometimes like a whole body spasim for an instant and then relaxed again.
4. Animals - one way bak mei incorporates animals is via the body posture which is called hum hung bart boy. ie tiger back, dragon waist, monkey stomach and chest, eagle vision and spirit shown in the eyes, etc. Another way is via the mindset. Bak Mei is a tiger system and, when taught right, very aggressive.
One thing different between Bak Mei and SPM is the dynamic tension which is in SPM at the start. But realy the two powers are much the same in the end. The power is the same its just developed in a different way. I think the iron shirt that are in both systems are much the same as well. This type of iron shirt is a result of the power generation method which is based very much on breathing, luk hup, fau chum tun tou, hum hung bart boy, and the stance. Thus a strike them when being struck or strike when they move mentality is used to great effect. Strike with ging and you will not get hurt.
Yau Kung Mun has a set called Ying Ching which has alot of dynamic tension in it and I think sort of bridges the gap. Though the set is not from SPM. Truly if you want to get a good feel for what Bak Mei is realy like in application and see some application clips that are good go to www.yaukungmun.com.au and check out the technique workshop page. Now people might get p i s s y by me putting that up but realy you will find no better site.
And check out that bakmeiquan forum. Myself and Tao Yin have been posting on there for a while now. And there are some who know alot on there though they post little.
