I would like to be able to make my printed images 4-5 ft long.
Thanks in advance.
Keep in mind that you want your images at 150dpi, so if you are starting with an image that is 72dpi, to get it to 150dpi (without losing or creating any data), your 2000x3000 image at 72dpi is the same as a 960x1440 at 150dpi.... Not big enough for a 4-5 foot long image without some noticeable softening when enlarging the image.
Now, Casino is an older movie, so finding quality images, as you are finding, is hard, let alone images that have some decent size to them. I've done some looking for another AVS member for a Casino poster in the past, we we never really had any good luck with it and it got dropped from his list of posters.
Now if that was 2000x3000 at 150dpi, then you would have a great size to work with for a larger printed image.
Can you use a different, newer movie instead? There would be better luck in finding an image that would be larger to start with.
