Prime currently (August 2020) has Dressed to Kill up. Unfortunately this is NOT the unrated edition but the R-rated edition with significantly less blood and less beaver. JUST SAY NO! I encourage fans to seek out the beautiful Criterion Collection bluray with enlightening extras including a very imformative interview between De Palma and über-fan Noah Baumbach.
I don't think it's still on Prime but it's currently (November 2020) on the Criterion Channel with the full Unrated version and all the Criterion extras imported from their Bluray.
i saw it just popped up on criterion the other day.
i've seen dressed to kill a few times over the years, but never the unrated one, i'm pretty sure. i didn't know there was such a thing, tbh, so thanks for the heads-up. i'm definitely going to bump this to the top of my watchlist now that i know...
Prepare for more blood and more beaver. If you look the title up under "Collections", you'll see all the Criterion.extras. One of the segments compares the Unrated, R-Rated, and Network versions so you can see what was cut out for US theatrical release and TV airings circa early 80's.
one of my favourite things about criterion's streaming service is that they include the extras for so many of their titles. wish they had all of them, but i'll take what i'm given.
