First Trailer for 'The Book of Eli'

Denzel looks pretty tough in this, and it appears from the trailer that Gary Oldman returns to his bad guy days, ala Zorg (Fifth Element), Drexel Spivey (True Romance), or Stansfield (Léon). I had no idea Oldman was even attached, so now my curiosity is piqued! The main problem I have is that this seems to have similar themes to John Hillcoat's 'The Road' which comes out a few months earlier than this (Oct 16th '09 vs. Jan 15th '10).
