Remakes: "Solaris" by Andrei Tarkovsky (1972) and "Solaris" by Steven Soderbergh (2002)

Seminar paper from the year 2004 in the subject Communications - Movies and Television, grade: 1, Utrecht University (Media Studies), course: Remakes & Parody, language: English, abstract: Thom Patterson from CNN expresses the issue of the remake in a very nice way: "Remaking well-known films can be the Hollywood equivalent of replacing the family dog or a favourite bathrobe: sometimes only the old one will do and a replacement is unthinkable."
In my case study I will take a closer look at the two different versions of
"Solaris":
Andrei Tarkovsky's "Solaris" (1972) and
Steven Soderbergh's "Solaris" (2002)
Is Soderbergh's "Solaris" a worthy representative, replacement or addition to Tarkovsky's "Solaris" or is it just like Patterson describes it, unneeded like the replacement of the family dog? Is Tarkovsky's "family dog" so well-known and respected that a new "family dog" would be redundant?
First of all, one should notice that both films are based on Stanislaw Lem's book "Solaris". At least that's what one can read everywhere...but is this so? Is Soderbergh's film a re-adaptation of Lem's book or is it rather a remake of Tarkovsky's film?
I would like to analyse in what way the two directors developed the characters in the film having the book "Solaris" as the basis.
By analysing the way, Soderbergh and Tarkovsky present the relationship between Hari/Rheya and Chris and how the two directors develop the characters, I will also try to find an answer to the question whether Soderbergh's "Solaris" is a remake of Tarkovsky's Solaris or a re-adaptation of Lem's book.
What are the similarities and differences of the presentation of this relationship in the two films?
Soderbergh for example never personally said that his film is only a remake of Tarkovsky's "Solaris" but also, or even more, a re-adaptation of Lem's book.
This would exactly apply to the theory of Jan Speckenbach, who mentions in his first part of "On th
