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 Lehár ("The Merry Widow") 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.
