The dynamics of the poles of the two--soliton solutions of the modified Korteweg--de Vries equation $$u_t + 6u^2u_x + u_{xxx} = 0$$ are investigated. A consequence of this study is the existence of classes of smooth, complex--valued solutions of this equation, defined for $-\infty < x < \infty$, exponentially decreasing to zero as $|x| \to \infty$, that blow up in finite time.
