A production spokesman for the Allman Brothers biopic has spoken out about an onset tragedy, which claimed the life of an unnamed camera operator's assistant.

The Midnight Rider crew member was killed in a train accident in Wayne County, Georgia on Thursday (20Feb14).

Reports suggest a train unexpectedly travelled down the tracks while the crew was carrying out camera tests for the film, killed the woman and left seven other crew members injured. Two were left with serious injuries, and transported to a local hospital.

A spokesman for the film tells Wenn, "All of us on the production team are devastated by the tragic accident. Our thoughts and prayers are with the family of our crew member.”

The film, based on Gregg Allman's New York Times bestselling biography My Cross To Bear, officially begins filming on Monday (24Feb14). It features William Hurt and Tyson Ritter as the older and younger Gregg Allman and Wyatt Russell as his brother Duane.
