Nitpicks: In the teaser, when Dylan is shooting at bottles to test Harper's new gun, there are several issues. To begin with, Dylan shoots his first bottle, which breaks, then a large piece shifts and falls a second later, a highly unlikely result of a round hitting a bottle at high velocity. He then shoots all the rest of the bottles in the line-up, then talks to Harper for awhile. Then he turns back and shoots another bottle, though there were none left unbroken previously. Lastly, the final broken bottle breaks exactly the same way as the first bottle did, and since it broke in a highly improbable fashion, it's extremely easy to see that they just reused the same footage for both shots.
