We prove that if ϕ is an analytic function bounded by 1 on the bidisc D 2 and τ is a point in a face of D 2 at which ϕ satisfies Carathéodory’s condition, then both ϕ and the angular gradient∇ ϕ exist and are constant on the face. Moreover, the class of all ϕ with prescribed ϕ (τ) and∇ ϕ (τ) can be parametrized in terms of a function in the two-variable Pick class. As an application we solve an interpolation problem with nodes that lie on the faces of the bidisc.
