Becoming the new Russian tsar is about as easy as it sounds-doubly so for the young Alexej, the shy young prince who finds the burden of leadership suddenly thrust upon him. The operetta by Austrian composer Franz Lehar ("The MerryWidow") receives a splendid production starring Wieslav Ochman, Teresa Stratas, and Harald Juhnke in key roles; Willy Mattes conducts the orchestra. 90 min. Standard; Soundtrack: German DTS 5.1; Subtitles: English. In German with English subtitles.
