Split CEOs destroyed Warner Bros. Paramount just hired the same trap

Paramount's new co-CEO structure is not a puzzle waiting to be solved. It is a replay with a known ending. Ynon Kreiz will manage day-to-day operations while David Ellison steers creative vision and strategy. This arrangement has already failed visibly at Warner Bros. , where it produced 18 months of accumulated friction before forcing out the creative officer.

The split is tempting on a spreadsheet. One leader optimizes for margin, speed, and quarterly targets. The other imagines what to make and who to hire. They should complement each other. They do not.

When Jason Kilar and David Zaslav held these roles at Warner Bros. in 2020, the architecture looked identical: operational leadership and creative vision separated by title. What it produced was paralysis on green-light decisions. A film or series proposal would move through creative channels on a timeline that asked: Is this artistically ambitious and will it build the franchise? Operations would receive it on a different timeline asking: Can we produce this within cost parameters that hit margin targets by Q3? These questions have different answers. More importantly, they have different time horizons. A creative executive can afford to wait 18 months for the right project. An operational executive cannot. The operator's calendar is a series of deadlines. The creative person's calendar is a series of maybes.

The tension is not personality—it is temporal. Kilar and Zaslav were both intelligent, both professional. They simply operated on irreconcilable clocks, and every decision became a negotiation between speed and imagination.

Paramount's merger close is months away. The new structure will face its first real test when the creative slate arrives at the operations desk and Kreiz has to decide whether an ambitious project fits the financial grid. If the history of Warner Bros. predicts anything, it predicts that Ellison and Kreiz will discover they are not building together—they are blocking each other. Someone will leave, or the structure will mutate into something else. The company will learn, as others did before it, that you cannot split the job of leading a studio in half.
