Producers for the stoner buddy comedy franchise “Harold & Kumar” say the fourth installment remains in active development. Greg Shapiro, a producer on the series, confirms at the Karlovy Vary Film Festival that “Harold & Kumar 4” is still set to happen, with the core team returning. Shapiro says the screenplay work is underway, and that the project includes the key writers and actors from the earlier films. He characterizes the status as “on track” and expresses a goal of moving quickly into production, adding hope that filming will begin soon. Both outlets report that Shapiro’s comments point to continuity in creative and performance roles, rather than a reboot or major recast. No release date, production schedule, or additional casting details are provided in the coverage. The remarks are framed as a development update rather than an official announcement of concrete timelines, but they indicate the project has progressed to the script stage with the series’ established participants involved.
