I will give a review of recent developments in the theory of scattering amplitudes in supersymmetric gauge theory. In particular we will discuss the duality between amplitudes and Wilson loops in the planar N=4 gauge theory. The duality implies an extra hidden symmetry of scattering amplitudes - dual superconformal symmetry. When combined with the original superconformal symmetry of N=4 Yang-Mills, it becomes a Yangian symmetry, hinting at the integrability of the gauge theory scattering problem.
