EXCLUSIVE: HBO has passed on the half-hour comedy pilot Spring/Fall. Set in New York City against the backdrop of the fashion world, the project centered on the dysfunctional partnership between Margo (Tea Leoni) and Eden (Hope Davis), two women with different approaches to career, family and friendship. Kate Robin wrote the pilot, which was directed by Jake Kasdan, with R.J. Cutler executive producing alongside Leoni and Robin. Since doing Spring/Fall together, Robin and Kasdan have teamed for a new project, a female-driven drama, which sold to Fox last month with penalty. Meanwhile, Leoni has already been approached for new pilot lead roles.
