'Transformers 3' Tragedy Latest Hollywood Stunt Gone Wrong

Sept. 6, 2010 — -- Once again, the set of a movie has become the scene for unforeseen tragedy.

Gabriella Cedillo, 24, an extra on the set of "Transformers 3," is in a medically-induced coma after reportedly suffering a head injury while driving a car during a stunt on the film's Illinois set.

While local news reports say Cedillo was struck by a cable that snapped and sliced through her car, representatives for Paramount, the studio producing the Michael Bay-directed movie, told Deadline Hollywood that her car was not involved in the stunt and a "freak accident caused her injury."

The "Transformers" mishap is just the latest to happen during the making of a Hollywood picture. Below, five of the worst on-set disasters of all time.

1. "The Twilight Zone's" Triple Death. The making of Steven Spielberg and John Landis' 1983 "Twilight Zone" movie turned tragic when a helicopter accident claimed the lives of actor Vic Morrow and two child actors, Myca Dinh Le (age 7) and Renee Shin-Yi Chen (age 6). Pyrotechnic explosions caused the low-flying helicopter to spin out of control and crash. The incident led to legal action against the filmmakers, particularly Landis, who directed the segment involving the helicopter. While ultimately, no one was found criminally culpable for the accident, it led to tightened regulations on the use of child actors in special effects-heavy scenes.

2. Brandon Lee's "Crow" Killing. A budding action star's career was cut short when Brandon Lee -- son of famed martial arts actor Bruce Lee -- was accidentally killed on the set of 1994's "The Crow." The film involved a sequence in which a villain was supposed to fire a gun at Lee as he walked into the scene. Unbeknownst to the crew, a bullet was lodged in the prop .44 Magnum used during the filming, and Lee was fatally shot in the abdomen on set. He was 28 years old.

3. "Top Gun" Tragedy. Famed acrobatic pilot Art Scholl was hired to do in-flight filming for Tom Cruise's 1989 hit "Top Gun," but an accident claimed the veteran performer's life when his Pitts S-2 camera plane failed to recover from a flat spin and plunged into the Pacific Ocean. The exact cause of Scholl's crash remains unknown, as neither the plane, nor his body, were ever found. "Top Gun" is dedicated to the memory of the 53-year-old pilot.
