I had a look in O'Brien's 2nd edition, in the chapter on Marx. Marx did put out a series of Historical Chinese Warriors. Your first figure bears a stylistic resemblance to those figures, though I do not think it is of that series. Those figures each had weapons and were posed more dynamically. Also, they were issued with a small, round pedestal base, under the molded base cast with the figure.
I haven't found anything yet like the camera crew, and I'll defer to Scott's suggestion, till I can check through the rest of my references.
Prost!
