I look forward to see the movie.

The other thing I suppose, is that the people won't be called as Sloveni, but Slovania. The difference is, Slovania means common, undefined Slavs and Sloveni means Slovaks till the 15.-16. century (that's why Slovenky, Slovensko, slovenský, slovenčina).

Whether the Slovaks already existed as a separate nation? How can you be sure?
