It's a prequel but shouldn't be watched before.
The series is about investigating the murder of Laura Palmer.
Fire Walk With Me is a film the follows the last week of her life, don't watch it until the series has revealed who killed her, otherwise you are in for gargantuan spoilers.
I'd recommend watching it between Twin Peaks and Twin Peaks:The Return.
Thanks man, the last thing I wanted was to spoil something for myself
Mulholland Drive is one of my favourite movies ever. If you haven't seen it in English yet, then I highly recommend it. Blue Velvet is also a great movie and one of the best I have ever seen.
Those two movies I've been wanting to watch for the longest time, but they're simply not available at the moment on neither of the services I use, and instead of using illegal streaming services (which I'm trying not to do anymore), I figured might as well watch the gazillion other things available which I'm already paying for, and just wait until other stuff comes up...
I actually just rewatched
American Psycho the other day; I've almost forgotten how good that movie is and how insanely good Bale is in it, but one thing I think I haven't noticed before...it's how
hilarious the movie is!! Last time I saw it was many, many years ago, and I guess my sense of humor hasn't matured into the dark hole of existence where all souls vanish which is nowadays, but man, this is some real black humor! Bale's performance seen as dramatic is great, but when you see it from the comedic point of view, it's simply incredible

and I remember seeing Mary Harron mention that all the killings in the movie were real and that she regretted not making that perfectly clear, but once you accept the absurdity of the comedic tone of the movie from the get go, it's quite easy to see how someone like Bateman could perfectly get away with murder.... since nobody else really cares.
I used to love that movie, but now I love it even more... and what an amazing feeling that it!
