Drama surfaced on the set of Michael Bay’s Transformers 4 Wednesday after a fire broke out in the attic of 100-year-old home.

A rep for the Pflugerville Fire Department in Austin, Texas tells TMZ/a> that the blaze was possibly set from the movie’s pyrotechnics.
The home was the site of a controlled explosion that went wrong.

One injury was reported.

"There was one injury to a civilian who was transported to the hospital by Austin Travis County EMS. We have no other information on this person or their injury,” an official explains.

According to a report from Splash News, Mark Wahlberg helped grab equipment surrounding the house so it would not be damaged from the blaze.

Officials were on scene during the controlled explosion and were able to put the fire out almost immediately. Damage to the attic is noted as “substantial,” but the home has since been released back to the homeowners. The fire has since been ruled accidental.

Transformers 4 is set for release June 2014.
