Cedillo had been working as an extra Wednesday evening, filming a scene involving multiple cars when, according to Indiana State Police, a tow cable that was pulling her vehicle snapped and whipped around, smashing the windshield and striking the victim in the head.

After her car rolled to a stop a mile down the road along a concrete barrier, emergency fire and medical personnel were on the scene and a critically injured Cedillo was airlifted to nearby Loyola University Medical Center where she was listed in critical condition.

After the accident, production on the blockbuster sequel was halted and a shoot scheduled for Thursday morning in Chicago's Millennium Park had been canceled, though it's unclear whether the cancellation was the result of what had happened.

Reps for DreamWorks and Paramount Pictures, the studios co-releasing Transformers 3, have so far not commented on the matter.

Indiana State Police are probing the mishap.
