We calculate the electroweak and QCD corrections to $W^{-}{W}^{+}\to t\overline{t}$ and $ZZ\to t\overline{t}$. We also consider the interplay of these corrections with the effect of anomalous interactions that affect the massive weak bosons and the top. The results at the $VV$ level fusion are convoluted with the help of the effective vector boson approximation to give predictions for a high energy $e^{+}{e}^{-}$ collider.
