Verdi Productions,  Magna Entertainment and RDZ Productions are producing the documentary “Man in Red Bandana,” which focuses on late 9/11 hero Welles Crowther, Variety has learned exclusively.

The film is written and directed by Matthew J. Weiss. Chad A. Verdi and Joshua Sason are producing and Michelle Verdi exec producing. Magna is financing and exec producing.

Gwyneth Paltrow is set to narrate and Lyle Lovett is performing an original song.

Crowther was a 24-year old equities trader on the 102nd floor of the South Tower of the World Trade Center who’s credited with saving at least a dozen lives before the building collapsed. His heroics included carrying a woman on his shoulder down 17 flights of stairs.

His family was unaware of Crowther’s activities until his mother read a firsthand account in The New York Times of being saved by a man in a red bandana.

The film will include interviews, archive footage, re-creations and animation and will depict the diverse ways that Crowther is honored throughout the United States.

“This is story that must be told and is for the world to see,” Chad Verdi said. “My wife Michelle and I currently have four other projects on the books for 2017 but this is now first in line. It’s way too important of a story to sit any longer.

Verdi is meeting with buyers at the Toronto Film Festival, which is screening boxing drama “Bleed for This,” starring Miles Teller and Aaron Eckhart. Verdi is one of producers on “Bleed,” which premiered at the Telluride Film Festival on Sept. 2.

“As a lifelong New Yorker, there is no single day of my life that brings back more emotion and vivid memories than September 11, 2001,” Sason said. “Amidst the chaos, dread and sadness, there existed saint-like beings that put others before themselves. Welles’ story and how it has achieved folklore-like status throughout the United States is one of hope and selflessness that instills faith in the human spirit.”

Verdi and Sason will donate all net profits to the Welles Remy Crowther Trust.
