After Jeremy Renner suffered blunt chest trauma and orthopedic injuries from a near-fatal snowplow accident, his "Avengers" co-star Scarlett Johansson wasn’t sure if she would ever see her friend again. Johansson, 38, recalled the moment she learned that Renner had been crushed by a nearly 15,000-pound snow machine while he attempted to save his nephew’s car. "I was very upset," the Marvel star recounted during an interview with Variety.
