LOS ANGELES, Jan 4 — Marvel superhero actor Jeremy Renner said yesterday he was “messed up” after being run over by his own snow plow as he tried to climb into the driver’s seat of the giant 14,000-lb (six-tonne) vehicle.

Renner suffered severe injuries Sunday morning near his Nevada home while attempting to halt the PistenBully machine, which had begun rolling forward after he used it to help free a stranded family member’s vehicle from heavy snow.
