The action on the set of 'Transformers 3' got a little too real and seriously injured extra Gabriella Cedillo during a stunt in the Chicago area on Wednesday. The aspiring actress underwent head surgery a day later, and according to a CBS 2 report, is currently in stable condition.

The 24-year-old's mother and brother confirmed with CBS following the surgery.

However, according to, sources on set report that the operation was specifically brain surgery.

Fellow extra Blaine Baker spoke with ABC 7, detailing the horrific accident.

"The vehicle was being towed by another vehicle," Baker told ABC. "The cable between the two vehicles broke. It whipped around and sliced through the woman's car and sliced through her skull, apparently."
