We consider non-compact Calabi-Yau threefolds that are fibrations over compact Riemann surfaces, the local curves, and study the dynamics of B-branes wrapped around the curves. We discuss different but closely related possible approaches to this problem. In particular, we study the open topological string field theory of the B-brane and the dimensional reduction of the holomorphic Chern-Simons functional to the curve. The classical (g_s = 0) limit of these dynamics for one single brane is given by the deformation theory of the curve inside the Calabi-Yau threefold; we consider this last approach for the Laufer curve case.
