A River Runs Through It (1992) - Robert Redford 

Not gonna lie, I watched this because I was supposed to read the book for a class and didn't get it done. There's plenty to like about it, some great location photography and well this pretty much is what made Brad Pitt a star. Can't say I know anything about fly fishing or ever want to venture into Montana for any reason ever in my life, but I could still understand the fascination inherent in these characters.
