I don't know how these "free movie" sites work, never having used them. I have no idea if they're legitimate or not, though since they're so public it would seem they'd be easily shut down. Perhaps they license the films, perhaps they don't. And why they have access to stream them but Netflix doesn't -- no idea. But if you're interested, here are two of the sites I came across. There may be a subscription fee (which somewhat defeats the purpose of "free," though once you subscribe that's where the "free" kicks in) -- but the OV Guide site here shows a Free Trial button. Or there may not be a subscription fee, as the Snag Films site here somewhat suggests.
That aside, there's a very nice article about the movie on the New Orleans Times-Picayune website here for the film's 25th anniversary DVD re-release two years ago. Among other things, it notes that director Glen Pitre got a big boost towards making Belizaire the Cajun after he had been invited to attend a month-long "boot camp" at the Sundance Institute.
And finally, here's a trailer. Voyez la bas.
