How many of his movies do you own?
Unfortunately, I haven't been able to find all of them on DVD (I watched Two Bits and Author! Author! online, as well as Manglehorn before it came out. Dog Day Afternoon I can find, but for whatever reason saw it online.), but usually I make sure to find a psychical copy. Hell, I even bought The Son Of No One, which was a very crappy movie, but I don't regret buying since I'm a completist.
I have:
Panic In Needle Park
The Godfather trilogy (Well, I don't, but my dad does. And I will buy it myself one day.)
Serpico (My dad owns it)
... And Justice For All.
Scarface (My dad owns it)
Revolution (Give it a chance, it's an underrated movie.)
Sea Of Love
Frankie & Johnny
Scent Of A Woman
Carlito's Way
Heat
City Hall (Flawed, but enjoyable for what it was)
The Devil's Advocate (Got it as a birthday present, thank you sister)
Insider (My mom owns it)
Any Given Sunday
Insomnia
S1m0ne (This one is not bad either)
People I Know (It was okay, but a sad case of missed potential)
The Recruit
Angels In America (Haven't watched it yet though)
Two For The Money (Another "just okay" case)
88 Minutes (A real mess, but the unintentional comedy keeps it somewhat afloat)
Righteous Kill
You Don't Know Jack
Son Of No One (Complete crap)
Stand Up Guys
And recently, I also bought Danny Collins. I can't wait to see it!
You?
