It is shown that in a scalar quantum field theory at high temperatures we can compute even time dependent observables from an effective theory, which can be interpreted as a (nonlocal) classical statistical field theory. We examine the retarded Greens function in the local approximation, and define the classical self energy. Its imaginary part agrees with the quantum case in the leading order.
