  In this talk we present an update of model predictions for the $\gamma
\gamma$ total cross-section in the TeV region. The update includes preliminary
results for $\gamma \gamma $ cross-sections using the Bloch-Nordsieck model for
the overlap function of the partons in the transverse space, use of the CJLK
parametrisation of the photonic parton densities that has recently become
available and extension to the higher $\gamma \gamma$ energies relevant to the
planned CLIC collider.
