I expect the Russian and American versions of Solaris will necessarily be as different from each other, culturally, cinematographically, every which way. I will be surprised if a condensed version of the original movie (from a time length criteria) will be able to capture the nuances and the complexity of the novel. However, the American version, may reveal a lot about American approaches to difficult, dense subjects, and in that way, it may be interesting to see what is left of the book and how well known actor handles such material.
