EXCLUSIVE: HBO has decided not move forward with 40, the comedy pilot from Entourage creator Doug Ellin. The single-camera ensemble originally revolved around four lifelong friends — played in the pilot by Ed Burns, Michael Rapaport, Michael Imperioli and Adrian Pasdar — who help each other navigate life at 40, which isn’t all they expected it to be. After the pilot was shot in the fall, HBO and Ellin took a stab at reworking the project with rewrites, but the network ultimately opted not to proceed. Ellin is under an overall deal at HBO and will continue to develop for the pay cable network. In addition to 40, he also executive produced the HBO drama pilot Da Brick last year, which remains in contention.
