Part of the issue is you search differently with Google. Most users treat their keywords as circles in a venn diagram - the top result being the center.
Try being a little more explicit with DDG. Add the year a movie came out, the first and last name of a person + their title if it's a common name, things like that.
Also an aside, "!s" routes through startpage, which proxies a google search for you - much more private but still leveraging the Pagerank algorithm.
