I intentionally chose films with accessible releases (though perhaps not as friendly to the 'free streaming' world). All except Ema are available to rent for a couple bucks on Amazon Prime Video.
Assassination Nation has a region A blu-ray release from Universal
Ema has a region-free blu-ray release from Mubi
Margot at the Wedding has an R1 DVD release from Paramount
Mauvais Sang (i.e. Bad Blood) has a region A blu-ray release from Kino
Miller's Crossing has a region A blu-ray from Fox, that isn't outrageously priced yet (though if this wasn't a title prioritized during the Fox OOP crisis, I'd jump on that now regardless of your vote)
It also seems like Assassination Nation is available on Hulu for free for those with subscriptions, but I don't have one so I can't be 100% sure. Additionally a few other films here are free on Hulu with some add-on subscriptions like Showtime or whatever. I don't have TV channels or HBO Max or anything, so I can't comment about what's on there.
