Ralph Fiennes, who starred in "Onegin," appeared in "Harry Potter and the Goblet of Fire" and "Harry Potter and the Order of the Phoenix" with Gary Oldman.
From IMDb: "Onegin" is a charming and dramatic romance. It contains all of the elements of a great film. The acting is underplayed. The cinematography is perfection itself. The colors are muted in concert with the drama itself. One can only desire an extension of the romantic relationship with Onegin himself and his lovely sweetheart. There are very dramatic moments including the duel on the pier. The snow scenes are reminiscent of "Dr. Zhivago." I can highly recommend this picture for those romantics at heart. Alexander Pushkin would be proud to see this serious play in cinematic form. It is now in DVD format with excellent soundtrack and special features. This is one not to miss.
Trivia: Lots of Fienneses in this one. The director, Martha Fiennes, is the sister of star Ralph Fiennes. The composer is Magnus Fiennes (Ralph's brother). Sophie Fiennes (another sister) also appears in the credits.
