Well, the best way was already suggested. Vudu.
If you have a device that supports it (all three major game consoles do, as do many blu-ray players), you can see a few select titles. Right now you can watch "Goon" on Vudu, and that is still in theaters. So is the Halle Berry movie, "Dark Tide" (in fact, it was a pre-theatrical release viewable on Vudu.) Tomorrow they'll stream "God Bless America", a Bobcat Goldthwait comedy, before the theatrical release.
Plus, they tend to get movies on or before the DVD/BD release date, well ahead of Redbox or Netflix most of the time. Yes, you pay more, but that's how it goes. And you said money is no object.
Apart from that, no, there is no other outlet, unless you're well connected in Hollywood.
Don't believe everything on the Interwebz! A duck's quack DOES echo!
