The production of heavy leptons through the reaction $e^{+}{e}^{-}\to L^{+}{L}^{-}$ is considered in a model in which the weak interactions are mediated by the exchange of a heavy scalar. It is found that the weak contribution to the production cross section can be large, in fact, larger than the contribution from the electromagnetic interaction in some cases. Decays of the heavy leptons and angular correlations of their decay products are calculated.
