Mark Ruffalo has condemned the approved Paramount-Warner Bros. merger, stating it will "stifle creativity, weaken free speech, and cost people their jobs". The deal has been approved and is set to close next week, despite a grassroots campaign against it involving hundreds of thousands of supporters. Ruffalo characterises the merger as a bad deal for the country that should never have been approved, and insists the movement against it will not fade away, framing it as part of a broader fight against corporate consolidation benefiting billionaires at the expense of everyday people.

Over 5,670 filmmakers and more than 75,000 additional supporters have signed petitions opposing the merger. Ruffalo had recently urged California Attorney General Rob Bonta and a coalition of 11 other state attorneys general not to settle their lawsuit against the deal, which would permit David Ellison to acquire Warner Bros. Discovery through Paramount Skydance. The actor emphasised that the attorneys general work for the people who will be harmed by the merger and urged them to reject a deal he characterised as "filled with empty promises".
