  We describe predictions for top-quark pair differential distributions at
hadron colliders, which combine state-of-the-art NNLO QCD calculations and NLO
electroweak corrections together with double resummation at NNLL$'$ accuracy of
threshold logarithms and small-mass logarithms. This is the first time that
such a combination has appeared in the literature. Numerical results are
presented for the invariant-mass distribution, the transverse-momentum
distribution as well as rapidity distributions.
