“I’d do it again,” he tells a shocked Diane Sawyer in his first sit-down interview since the freak accident. “Yeah, I’d do it again because it’s going right at my nephew.”

The interview, which will air in full on Thursday, April 6, shows Renner reflecting on the excruciating pain he felt when he believed he was “dying” after being hit.

“[I felt] all of [the pain],” he shares before brutal audio of his 9-1-1 call plays. “I was awake through every moment.”

Despite his injuries, which include shattered ribs, a broken mandible, broken leg and so much more, the “Avengers” star hopes one day to get back to performing his own stunts.

“I chose to survive, it’s not going to kill me, no way,” he says of his injuries. “I’ve lost a lot of flesh and bone in this experience, but I’ve been refueled and refilled with love and titanium.”

Renner, 52, was run over by his own snowplow on New Year’s Day when he pushed his nephew out of the rolling machine’s way.

He sustained “blunt chest trauma” that required him to be airlifted and to undergo emergency surgery.

The “Hurt Locker” star returned home from the hospital a couple of weeks later and started documenting his intense rehabilitation and upright exercises, which he began just two months after the accident.

“Whatever it takes,” he captioned a video of himself working out.

Renner’s “Ant-Man and the Wasp: Quantumania” co-star Evangeline Lilly called his recovery a “miracle.”

“He’s made of something really tough, that guy,” she said last month. “You’ve always been able to see that in him. He is recovering incredibly, and I’m so grateful.”
