To a degree, I agree with you. Nonetheless, I can see NO legitimate reason to make a movie/miniseries about South & Southeast Texas in the Winter & Spring of the coldest/wettest 12 months in Texas history in a desert area. = The area south of San Antonio and east to LaPorte, where the major part of our Revolution occurred, were coastal plains, sloughs, creeks, rivers, swamps, bayous, etc.
(I'd bet that in 30 days or less that I could rent suitable filming locations to film a story like TEXAS RISING and within 100 miles of where those events actually happened - There are a LOT of large ranches in south TX.)
May I also add that there are MANY re-enactors who would likely "swarm" into south TX on the hope that they could be IN a HC/PC movie about early TX.
(IF I have anything to say about the filming, we will use REAL AmerIndians, as there are PLENTY of Tsalagis, Comanches & Apaches, who will want a job.)
Should I get to write/sell the mini-series for cable TV, we will, I feel sure, use FEW "name" actors & will find technical advisors who KNOW Texas history. = I've been involved in the production of two WBTS movies & we had little trouble with either finance, finding advisors, getting a director who wanted to try to do things correctly & people who were amenable to direction.
(GETTYSBURG & GODS and GENERALS were far from HC/PC but neither were they TEXAS RISING, GUNSMOKE or TRUE GRIT either.)
Also, clothing, weapons & horse tack that would look "realistic" in a movie (though those items wouldn't stand a close inspection by a "stitch counter") wouldn't be that difficult to do.
just my OPINIONS, satx
