Movie repository for storing movies based on country
One thing - this design is based on a false premise - that there is only ever a single title within a given country. See for example this movie which has 3 USA titles (albeit only one, final, official title). This can be fixed by changing the Country key of the hash map to a TitleType (which will often be just a country).

Another problem is that Movie isn't really an object - it doesn't implement any member functions. In fact, your RottenTomatoesTitleFinder works by directly manipulating Movie properties rather than calling Movie member functions. This is a violation of basic OO principles.
