Some A-list Hollywood talent didn’t wait until Thanksgiving to give back.

Filmmakers Sam Raimi, Catherine Hardwicke, and Ted Melfi joined Johnny Depp, David Lynch, J.K. Simmons, Laura Dern, Penelope Ann Miller, Richard Chamberlain, Jade Pettyjohn, Chad Coleman, Pritesh Shah, and Keith Allan to help make a dream film project come alive for Anthony Conti, a 16-year-old who is facing down stage IV adrenal cortical cancer.

Make a Film Foundation — a nonprofit launched in 2007 by Tamika Lamison (who also works as a researcher/consultant in the Education Department at the Academy of Motion Picture Arts and Sciences) that grants film wishes for children with serious or life-threatening medical conditions — collaborated with Conti to get the short film off the ground, a zombie project called The Black Ghiandola which Conti wrote with Scott Kosar (Texas Chainsaw Massacre) and additional writing by Wash Westmoreland (Still Alice).

Black Ghiandola tells the story of a young man, played by Conti, who risks his life saving a young girl he has grown to love after his family has been killed during a zombie apocalypse. Producers included Lamison, Adele Rene, and Bettina Fisher, with supervising producers Peter Farrelly and Sean Furst.

The three directors, Raimi, Hardwicke, and Melfi, took turns behind the camera during the five-day shoot, which Lamison described as a magical piece of “guerrilla filmmaking.” The project, which went before cameras in mid-November, marked the fastest preproduction and production schedule in Make a Film Foundation’s history. The organization, which typically plans each project out for almost a year, saw Conti’s idea go from conception to set in one month, all with the help of the aforementioned talent who generously donated their time.

“Anthony is an alchemist — there was magic happening all around the set,” Lamison tells The Hollywood Reporter. “It was like a magnet that kept attracting the best in so many people and attracting the extraordinary ‘yes’ at every turn.”

Among those offering support, according to Lamison, were Teamsters Local 399 drivers, Star Waggons, Wooden Nickel, Panavision, AMPAS, AMC, The Walking Dead, L.A. Grips, Plan U Prods., St. Joseph’s Hospital, Big Sky Ranch, Friar Tux, Nature’s Bakery, Gala Minasova’s Picture Car, Western Costumes, Essential Water, Cinepower & Light, Avon, Galpin, Quixote Rentals, Zio Rentals, Durable Medical Equipment Aid Society, Enterprise, Alex’s Catering, Skye Props, Boston Mass General, Bear Creek Restrooms, Ruskin Theatre, Constantine FX, Bloodlust Unlimited, MovieInsure, Domino’s, Starbucks, Warner Bros., and Anthony’s father, Brian Conti, and grandmother, Anita King.

“It was remarkable in the energy of giving,” she notes.

Conti’s project is the fourth film to come out of Make a Film Foundation’s premier program, the short-narrative program, which sees participants write and star in the their own short films with notable names joining them in the creative process. According to Lamison, Conti discovered Make a Film Foundation on his own, eventually reaching out to request a copy of one of its short film projects, The Magic Bracelet. After watching it, he hoped to collaborate on his own film and he reached out several times. Those plans sprung into action when his child care specialist, Jessica LeSage, sent Lamison an email informing her that Conti had exited a summer film camp due to his diagnosis.

“His film has nothing to do with cancer. It’s him making his film, his way,” Lamison notes of Conti, who also recently participated in an Academy experience that included a screening of his previous short film Twinkle, Twinkle on the big screen at the Samuel Goldwyn Theatre, and a surprise video clip showing a shout-out from the cast of The Walking Dead. “What I love about Anthony is his courage, his sense of humor, his profound sense of self, his huge heart and intensity as a human being and a filmmaker. We are all better for having Anthony Conti invite us to be a part of his life and his film.”
