Although I've yet to see American Hustle and The Wolf of Wall Street, I have seen three, rather good, rather small films that I can definitely recommend. Don't think their available for rental just quite yet, so keep an eye out...
Dallas Buyer's Club traces the very abrupt journey of a hard core, Texan homophobe's transformation into an AIDS's fighting activist (when he contracts the disease himself in the '80s).
Can't help but think back to The Deer Hunter (one of the most over rated pieces of crap ever created) when viewing Out Of The Furnace; it's set in an nearly identical albeit updated backdrop. But I like the slow, deliberate pace of this film (one can almost feel the humidity of the hot summer sun on your skin)- in contrast to Woody Harrelson's intense and truly intimidating White Trash, villain extraordinaire (worth the price of admission alone).
And finally there's Philomena, an interesting journey back into the Catholic guilt, abuse and denial of Ireland's past, and it's legacy into the present.
