i watched
Sharpe's Rifles -
yep,. that's a youtube link - available in full, in clear, for free.
It shouldn't be terribly obscure, because it's from 1993, but apparently Sean Bean - the guy who always dies? - had a looooong running TV series based on the
Bernard Cowell "Sharpe" series, comprising 24 original books (now 25) and
16 full-length TV films.
AFAIK they are meant to be fairly accurate, at least historically. I cannot vouch for the recreationism.
In this first film, Sean Bean is Sharpe, a newly-made lieutenant in what i gather is the 1809 War Of The Fifth Coalition. Sharpe is a sergeant, but by pure luck he saves a high ranking officer from death, and is granted an on-the-field promotion and an assignment for a secret mission - to locate and rescue a Rotschild, on his way to provide a bank loan meant to pay the British army during their Portugal campaign.
Sharpe is a man of the ranks, and as such he's not loved by his new unit, who believe the old adage that an officer is cut from a different cloth. It's clear that Sharpe faces not one, but two battles ahead of him.
It's fairly good stuff.
It doesn't look early 90s, more middle 1980s, there's lots of fake dying and crummy shooting scenes, but Bean is pretty darn tough as the no-nonsense Sharpe.
It would probably look bad to anyone under 40 but i found it .. pleasurably quaint.
My vote:
6.5/10, YMMV, depends how much you like Sean Bean.
