Recent theoretical progress in top quark pair production at hadron colliders

This is a writeup of a plenary talk given at the conference {\it HCP 2012} held November 2012 in Kyoto, Japan. This writeup reviews recent theoretical developments in the following areas of top quark physics at hadron colliders: (a) the forward-backward asymmetry anomaly at the Tevatron, (b) precision top mass determination, © state of the art NLO calculations and (d) progress in NNLO calculations.
