FISHINGTrout used in the movie were pond-raised in Montana and were kept in a specially aerated and cooled tank truck until their big moment in front of the cameras. No hooks were used, and no blood was drawn. A line was tied to each fish's lower jaw under the careful observance of the Montana Humane Society.
COSTUMESAbout 100 costumes were used for the picnic scene, 50 for the train station scene, and another 50 for the church scene. Since the church was filmed in all four periods, 50 costumes for each period were needed.
ACTORSCraig Sheffer, who played the writer Norman Maclean, is also a writer in real life. During filming, he kept a book in his trailer to scribble down his feelings during free moments between takes.
Tom Skerrit, who played the Reverend Maclean, visited Yellowstone National Park while filming A River Runs Through It. His then-13-year-old son visited with him and the two were very intrigued with the wildlife they saw.
