Melonie Diaz has plenty of reason to laugh…

The 29-year-old Puerto Rican actress, who earned critical acclaim for Spirit Award-nominated her performance in Fruitvale Station, has landed the lead in HBO‘s Laughs Unlimited (working title).

The drama series, which centers on a war vet’s struggles with post-traumatic stress disorder, has been in the works at HBO for several months.

While it hasn’t been picked up to pilot yet, the network is doing preliminary casting and working on the budget as it does on most scripts it is high on before making a formal pilot order.

Laughs Unlimited hails from Oren Moverman, who has directed Rampart and The Messenger, and Anthony Swofford, best known for writing the book Jarhead.

It centers on Army Reserve medic Billie Crown (Diaz) who, after fifteen months as a combat medic in Afghanistan, discovers that “real life” is just as perilous as war. Duty as a Sacramento cop offers the same dangers and thrills as combat, and repairing relationships with her husband and young daughter is as difficult as saving a comrade after an IED attack. Moverman and Swofford wrote the script

Diaz recently wrapped production on The Cobbler.
