Jeremy Renner Says He Feared He'd Be Just a Brain and Spine After Snowplow Accident

Jeremy Renner's incredible recovery has him in high spirits, but just after his horrific snowplow accident, he worried he would live his life as a shell of a human being.

Jeremy tells his emotional story of coming back from the edge of life to a point where he is mobile again ... with the help of a walker.

He worried in the days following the accident he would live the rest of his life as a brain and a spine, but not much else.

The "Avengers" star teared up as he spoke with Diane Sawyer about the pain he suffered and how he felt so sorry that his family was suffering as well. Jeremy was on the verge of tears as he told Diane he told his family he was sorry in sign language.

He looks amazing ... it defies what he went through. Jeremy is looking forward and says he refuses to be haunted by the accident that almost took his life.

He still has a ways to go, but all signs point to a return to normal life, which has gotta include acting.
