I wish someone would make a great movie about the Lewis and Clark expedition. I read the book Undaunted Courage about the Lewis and Ckark expedition. I am amazed how they were able to complete that long journey. They fought harsh weather, sickness , terrain , Indians , starvation, equipment and a host of other things that could go wrong. Can you imagine the movie this would be if produced the right way. Who would you like to see cast as the main characters. The scenery for such a movie would probably have to filmed in Canada now. If you want to read a good book , I highly recommend the book Undaunted Courage .
