Due to a strange mistake in the end credits Mykola Yeriomin's credit for direction is an implied one through Sergey A.'s one listed as "co-director". A's first credit in the main titles was actually meant for Yeriomin hence "music by", despite A. had no input in that area aside from music editing.
"Plumbers" credit in the main titles is misaligned and does not fit in the frame fully.
