title: Actin on multiple fronts to generate a muscle fiber.
abstract: How the actin cytoskeleton is harnessed to fulfill its diverse cellular functions is a recurrent and intriguing question. In this issue of Developmental Cell, Kim et al. and Massarwa et al. describe a new role for F-actin, and more specifically the actin regulator WASp, in myoblast fusion in Drosophila.
