'Transformers 3' extra Gabriella Cedillo was seriously injured during filming last month after a stunt went horribly wrong. And on Tuesday, her brother, Adolfo Romo, filed a lawsuit on her behalf against Paramount Pictures alleging negligence, RadarOnline.com reports.

"We filed a case this morning in Chicago and made a request for a jury trial," Cedillo's attorney Todd A. Smith told RadarOnline.com.

Her lawyer also said Cedillo, 24, is unable to speak and is paralyzed on her left side. "It looks like she has vision loss in the left eye, which is sewn shut because there's a paralysis associated with that and they don't want her eye to dry out." One day after the accident in September, Cedillo underwent brain surgery.

The suit refers to the victim as "a disabled person" and says that she "assumed no risk of injury in performing her duties as an extra on the Transformers 3 movie set."

Several different mechanical and procedural malfunctions are listed in the suit including: "Failed to properly weld the metal bracket to the stunt car... Failed to provide adequate safety precautions... Allowed untrained extras to drive their own vehicles within close proximity to a violent stunt."
