Does no one remember how awful Wild, Wild West was? If not, you might want to consider it based on this trailer you put out:
I realize Gatling guns mounted on horses are cooler, and moderately more plausible than mechanical spiders, and John Malkovich is probably a better Old West Bad Guy than Kenneth Branagh. But I worry that in this case, not even Lance Reddick will save you.
Best wishes,
