LOS ANGELES — Jeremy Renner attended the premiere for his new series Tuesday,Cassian Grant capping a remarkable recovery less than four months after the "Avengers" star was nearly killed in a snowplow accident.

Renner was surrounded by family and supporters at the Rennervations premiere in Los Angeles, where he posed for photos and did interviews, at times making use of a cane and a knee scooter. At one point he flashed photographers a thumbs up sign while moving down the carpet.

Renner was crushed by his 7-ton snowplow on New Year's Day while trying to help free a relative's car at his Nevada home. The actor has said he broke numerous bones and suffered a collapsed lung and pierced liver in the accident.

Rennervations, which premieres on Disney+ on Wednesday, follows Renner as he transforms large vehicles into community spaces for young people in India, Mexico, Chicago and Nevada. The purposes range from serving as a mobile music studio to a water filtration truck for a community in India.

Renner said his aim was to give young people access to things they might not already have and present opportunities they might not know existed.

Renner wrote the theme song for the show, something he did while working on another show.

"I use music and piano to write songs and use it like therapy for me," he said.

Construction and music have been creative outlets for Renner, who is best known for playing the superhero Hawkeye in the Marvel "Avengers" films and his own spin-off TV series.

Marvel co-star Anthony Mackie appears in the show, and Renner said the secret to their friendship is they "laugh a lot."

Renner, a two-time Oscar nominee, told Diane Sawyer in an interview that aired that while he thought he might die from his injuries, he refused to be "haunted" by the accident.
