Another excellent А/О example - "Россия молодая":
In this TV series the protagonist Ivan Ryabov (he is a real historical figure, a Pomor, i.e. a Russian from the shores of the White Sea) speaks with beautiful northern А/О accent.
You may hear him, for example, at 44:50 where he is captured by the Swedes and pretends to agree to steer their ships and circumvent shoals on the track to Arkhangelsk, which the Swedes are going to destroy. He accepted the offer for a reward of 500 riksdalers, but in the end ran Swedish ships aground right in front of cannons of a Russian fortress. It is a very good TV series, based on a book of the same name. I remember Estionian guy helping Russians, Swedish spy in disguise of a Danish person (Denmark supported Russia because Russia opposed Sweden). This book/film definitely arouses Russian patriotic feelings
PS: In the scene which I described Swedes and Russians communicate with the help of English-Russian interpreter. I wonder how truthful this detail is...
