Unfortunately, for a foreign learner it is tougher than that. Singular nouns ending in "-а/-я" (typically feminine, which, nevertheless, have some nouns for males: папа, дядя, мужчина etc.) have a separate accusative irregardless of their animacy.
I think, the most amazing thing is the plural of "лицо". This noun means "face", and in formal contexts - "person", "individual". Depending of what you mean, Accusative plural will be the same as Nominative plural ("I saw people's faces") or Genitive plural ("An officer noticed individuals behaving in a suspicious manner").

It is safe to say that for DeclensionI (consonant-ending and neuter) and plural nouns the rule holds: Accusative is the same as Nominative for inanimate and the same as Genitive for animate nouns.
