Jeremy Renner wrote what he thought would be his final message to his family when in critical condition in the hospital after his New Year’s Day accident.

In a clip teasing his interview with Diane Sawyer, the Hawkeye star said, “I’m writing down notes in my phone – my last words to my family.”

He added, “If I was there, on my own, that would’ve been a horrible way to die. And surely, I would’ve. Surely. But I wasn’t alone — I was with my nephew. Sweet Alex. And the rest of the cavalry came.”

Sawyer’s full interview with Renner airs Thursday, April 6th on ABC.
