Chandler Canterbury, Anna Gunn, Frances O'Connor, Dylan Matzke and Daveigh Chase have boarded the indie drama Little Red Wagon, based on the true story of 12-year-old homeless-youth advocate Zach Bonner, according to Variety.

David Anspaugh is directing from a script by Patrick Sheane Duncan.

Canterbury will play Bonner as an eight-year-old living in Tampa, Fla., with his mother (Gunn) and sister (Chase).

In the wake of Hurricane Charley, Zach uses his toy wagon to collect water, food and clothing for families made homeless by the storm, which leads him to found the Little Red Wagon Foundation and create "Zach Packs," backpacks filled with life's bare essentials plus a toy.

O'Connor portrays a newly widowed woman and Matzke plays her young son who land up in a shelter after a series of hardships.

Production began Monday in Charleston, S.C.
