Did Rick and Robyn end up together in real life ??

They were friends, and both went far and wide around the world since the events of "Tracks", but from what I understand, they've crossed paths from time to time. With the film "Tracks" finally being released, they've been seeing much more of each other, and even making interview appearances together. I'm hoping that for the U.S. release in the fall, they both will be giving interviews again, along with Mia Wasikowska and Adam Driver. How about all four of them together? I would like that.

This is an excellent 10 minute interview with Rick Smolan, which answers so much re your O.P. Also, he talks about Mia and Adam Driver, the making of the film, and a new book called, "Inside Tracks" that will be coming out, combining his original photos with pics from the film that were based on his shots.

No idea from the film. It was long enough to have told you that wasn't it? But they also failed to answer whether or not she was a sick animal abuser who was compensating for a failed upbringing by torturing animals in order to become famous.
