I was really surprised by this movie. I did not expect it to be so good. I will even be bold to say, that the way Georgy Daneliya directed this film makes it more interesting and much much deeper than the original Mark Twain's material! The cast is also outstanding - some of the best Soviet actors of that time (and all times). I'd say it deserves a place among the best movie classics. Too bad it's not known to the most of the world. In fact, even I never heard about it although I was born in Soviet Union. I guess it's because officials didn't let it go widely, because it has some graphic violence and other elements not excepted by the official Soviet morality. There was another movie well known in USSR on Twain's novel about Tom Soyer, but it was for children. it's not really bad but it's completely different level than Completely Lost.
