Robert Halmi Jr. resigned Wednesday as prexy and CEO of RHI Entertainment, which recently emerged from Chapter 11 with a plan to reduce its debt by $400 million.

His father, Robert Halmi Sr. will remain with the company to continue overseeing production of its miniseries. Also out is chief operating officer Peter von Gal, who’s been with the company since 1996.

“RHI is in the strongest financial and operational position it has been in years to expand its production and distribution activities,” said Gabriel de Alba, chairman of the board of directors. “We greatly appreciate Robert’s enormous contributions and plan to substantially build on them as we take the company to the next level.”

The departure of the junior Halmi splits up a father-son team that spent several decades together atop one of the globe’s leading producers of long-form TV programming. RHI has produced hundreds of hours of movies and minseries including “Merlin,” “Gulliver’s Travels” and “Tin Man.”

“RHI is very near and dear to me,” said Halmi Jr. “I’m gratified to have been able to see it through a successful reorganization and put it on a path to thrive for years to come.”

The Halmis bought back their production company from Hallmark Entertainment in 2006, but filed for a prepackaged bankruptcy in late 2010 citing $600 million in debt.

While most of RHI is now owned by private equity firm Kelso & Co., the Halmis held on to 15% of the company.

Just last month, Halmi tapped Andrew Hines as executive VP and CFO for RHI.
