And why did Ivan become a tall and strong man after bathing in boiling water? Ultimately, the tsar always made unreasonable demands and met a tragic end?
Although the 1947 film has a simpler structure and is quite faithful to the original compared to the 1975 version, I consider its artistic meaning to be deeper. However, this is just my personal opinion, as each era will have a different perspective on a work, because they are always influenced by societal factors.
