River and keanu worked together on this and my own private idaho together, which is cool as i love them both(just a random thought) + (i thought i already posted this but can't find it which is wierd)!
Yeah, Heather, I think they became friends in this movie and planned to make MOPI too:) Actually Keanu was first friends with River's sister Rain, who then introduced them (I think it was her, yeah). It's great seeing them together on the screen:)
