George Lucas has always been a master when it comes to crafting stories, so I'm anxious to see how this works out. Right now, all the official release has is the synopsis and bonus features, which is probably all you want.
I have heard the best way to experience Interstellar is in an IMAX theater. This might top it (I have used an Oculus Rift before and it's gorgeous). Check out the pics below and enjoy the SXSW, if you happen to be attending.
