 In this talk, I will connect three topics: supersymmetric localization, bootstrap, and scattering amplitudes in string theory and M-theory.  In particular, I will explain how one can rederive the first few terms in the small momentum expansion of string theory and M-theory graviton scattering from CFT results.  I will also explain how our knowledge of closed string scattering amplitudes and supersymmetric localization can be combined to give new results for the 4-point function of conformal primary operators in 4d N=4 super-Yang-Mills theory and in ABJM theory at strong coupling.
