Alec Baldwin 'Rust' Actor Says Camera Was Protected During Shooting, Not Actors

The gun scenes in the Alec Baldwin movie "Rust" were considered dangerous enough to provide certain protections ... but not protections for people, but rather the expensive camera.

Ian A. Hudson, a New Mexico-based principal cast member who plays an outlaw in the film, tells TMZ ... his last scene in the movie on October 8 was a shootout where he was killed, and he says he was terrified that there were 20 rounds from pistols and rifles that were unloading blanks, and the only protection against a mishap was some sort of shield around the camera.

Hudson describes what he says was something like a 3X2 foot shield, with the only part exposed being the lens. He was standing 6 feet in front of the camera, and wondered why there was a need to protect the camera as he stood there exposed. He adds there were people standing behind the camera, something gun experts say should not have happened.

Hudson says he felt the scene was "life-threatening," because real weapons were being pointed at him and blanks discharged, creating a rush of air that struck him multiple times. He also said he was hit by small pieces of cardboard.

The actor told us he didn't complain because he was new in the business and felt he would be viewed as trouble if he voiced concern.

And, Hudson says, he and his fellow actors were alarmed enough to reference the accidental killing of Brandon Lee back in 1993. He told us they discussed the fact that it didn't seem like much has changed in the last 30 years.

Hudson says the other, more experienced actors checked their weapons 2 or 3 times after they received them from the armorer, and it didn't matter whether they were told the gun was "cold" or "hot." Baldwin did not check the weapon, but rather relied on the assistant director who assured him the gun was "cold."

The armorer, Hannah Gutierrez-Reed, is now under the microscope because of her inexperience ... something she talked about in a recent podcast. But, Hudson says director, Joel Souza, praised Hannah when Hudson was on set, telling her she was doing a good job.

As we reported, Souza was shot along with director of photography, Halyna Hutchins, who died from her injures after being hit by a live round.

Ian's character was killed in a shootout with Jensen Ackles' character ... and he says it was extremely unsettling.
