Paramount Skydance Corp.'s $110 billion takeover of Warner Bros. Discovery Inc. has hit a potential regulatory roadblock as European Union officials raise concerns about filmmakers reaching audiences in the bloc.

The European Commission's antitrust chief highlighted questions about content distribution access, suggesting the merger could limit how movies and shows get to EU viewers. This represents the first major hurdle for a deal that would reshape Hollywood's competitive landscape.

Antitrust scrutiny typically focuses on whether mergers reduce competition or harm consumers. In this case, EU officials appear worried that combining two major entertainment companies might restrict independent filmmakers' ability to distribute content across European markets.

The $110 billion transaction now faces a critical test that could determine whether the merger proceeds unchanged, requires divestitures, or faces outright rejection from European regulators.
