When movie producers can't even get the historical uniforms right, it's a sign they don't care about the film and just want to make a fast buck. And it's a shame because there some beautiful cinematography going on here, so someone involved in the production cared.
Just for future reference, West Point cadets didn't wear kepis in 1830. The kepi didn't show up in the US military for another 35 years. At this point, the cadets should be wearing the 1825 forage cap, which looked nothing like a kepi. The least the costume department could have done was get the hats right. Seems the producers had a bunch of civil war costumes laying around, and just decided to use them, instead of doing the bare minimum to get it right.
