Jeremy Renner was treated "like a child" on the set of 'Mayor of Kingstown' after his horrific snowplow accident.

The 53-year-old actor admitted he faced severe limitations when he returned to work as his body was still recovering from the accident, where he suffered blunt chest trauma and orthopedic injuries after attempting to help his nephew with a car issue.

He told the Los Angeles Times newspaper: "They have to treat me like I'm a child actor. The mayor of Kingstown is now like a 14-year-old.

"They go, ‘And action!’ And I was out. We discovered they worked me too hard, too many hours, too many days in a row. What I’m willing to do is everything, but what I’m able to do is a different thing."

Jeremy also revealed that 'Mayor of Kingstown' co-creator Hugh Dillion asked his mother for permission for him to return to set and Jeremy was unsure if he even wanted to.

He said: "To try to create some truth and then get the audience to believe it, while I’m just trying to learn to walk again, to put one foot in front of the other and not get up in agony. I’m doing all these things to find my footing on the planet again. The idea of going into a fictional world — I have to be honest with you, I had to really consider, Is this something I really want to do?"

However, Jeremy insisted the accident has left him with a more positive outlook on life.

He said: "It took the collective of all these people. That’s the power of love. It’s a slow burn. Man, I tell you...

“I’m alive. I’m walking through life with a smile on my face. And there’s nothing that’s ever going to change that. Nothing. It’s impossible for me to have a bad day."
