Shanghai Surprise (1986) - Original Trailer

I'm watching it on Telerompo.
Now, I don't know and I don't want to know if and why someone has or hasn't talked about this, which, on paper, seems like an INDISPENSABLE film.
Surely: given the caliber of the production (I believe it's by a certain Giorgetto Arrisone), the presence of Racchia Ciccona - who was all the rage back in the day - and the extraordinary acting performance I would have expected from the then chubby Scionpén (whose face for some reason reminds me of the collapse of a dam) made me think it would be a cult movie known only to refined connoisseurs, like #capish, but more "advanced".
But no.
It's a ridiculous mess!
