Mixed-martial-arts veteran turned actor Randy Couture said the cast was missing Stallone during promotion of the film, which includes a European trip and next week's Los Angeles premiere.
"He is the leader of this group, both on-screen and off-screen. And so we miss him here," Couture said. "But we understand. We're parents. We have kids. We can't really imagine what he's going through now. But what do you say? ... So we're giving him space."
