JA from MNPP here, taking a look and a listen at the whispers coming from Warner Brothers that no less than Joaquin Phoenix is being "sought" to play the bad guy in the next Superman (slash Batman slash Justice League) movie, which is thought to be a little somebody named Lex Luthor. "Sought" meaning somebody's floating the idea, and Joaquin hasn't even been offered anything yet, but hey it's the internet and we have to fill this place with something, so let's talk about it!
I personally was on a bit of a cold streak with regards to Joaquin for awhile, but then I thought he was the best thing going on in The Master last year, and then Her happened and in my review of that film (which is out in some theaters now! See it as soon as you can!) I called it "probably... when it all comes down to it, my favorite Joaquin Phoenix performance that will ever, ever happen." I stand by that effusive assessment here a few months later - indeed my affection's only grown. So Joaquin and I, we're totes good right now! And I kinda love the idea of him tackling a big bad super-villain.
Side-stepping over to the topic of whether it's a good idea to cram every character in the DC universe into Zach Snyder's next whizz bang opus though, well that's a bald horse of a different color. There are lots of Superman characters - Lex again? Really? And the stink off Man of Steel, which might've given me lasting brain damage, is making me wonder if Joaquin might be better off sticking to his auteur pieces anyway. What do we think?
