The long-rumored, long-gestating film known as Main Street is inching its way to realization.

Reliant Pictures, the Thom Mount-helmed company that is producing, has a production office at the old Duke Diet and Fitness Center at the corner of Trinity and Duke Streets, according to production manager David Linck.

Filming is now set to begin between March 30 and April 6, Linck says.

Last month, we reported that a New York casting agency had conducted a week of auditions for smaller speaking roles. Linck doesn’t close the door on additional casting, saying in an email, “Although no further cast and extras auditions are scheduled at this time, there may be more in the future as need dictates.”

Linck was unable to confirm the identities of the lead actors, despite reports of the involvement of Colin Firth, Patricia Clarkson and Ellen Burstyn. “Cast names are not set and not confirmed,” Linck says.

Reyn Bowman of the Durham County Visitor’s Bureau (DCVB) confirmed that his office has been assisting the advance team with locations and permits.

The script of Main Street was written by playwright and two-time Oscar winner Horton Foote, who died earlier this month at the age of 92.
