The welder claims a temporary control panel installed in a building at 2558 W. 16th St., was "negligently wired" to pump out 220 volts. He alleges no one warned him before he plugged in a grinder that needed half of that voltage, the Chicago Tribune reports.
The equipment started spinning violently causing "severe and permanent damage to his arm," according to the lawsuit.
A spokesperson for Paramount Pictures said the studio has not seen the suit and refused to comment.
The family of Gabriela Cedillo, a movie extra critically injured during filming, is also suing Paramount.
The 24-year-old Chicago woman was struck by an object that came through her windshield while she drove her car on the Northwest Indiana set in September.
Cedillo is permanently brain damaged, said relatives.
