Plot and subject

The film opens with the newborn So Wa-wai's diagnosis: jaundice damaged his brain at birth, leaving him with weak hearing and spastic limbs, and doctors doubted he would ever walk³^•⁷. His mother refuses to give up on him; under her demanding training he learns to walk, and a running talent emerges that takes him into Hong Kong's para-athletics team as a teenager³.

The story follows mother and son across roughly three decades, capturing the Hong Kong of the 1980s and 1990s and So's Paralympic career⁸. In the film, the 13-year-old So (played by Fung Ho-yeung) is recruited into the city's para-athletics team by coach Fong (Louis Cheung Kai-chung) and wins his first gold medal as part of the Hong Kong men's 4×100m relay team at the 1996 Atlanta Paralympics⁹. The adult So is played by Leung Chung-hang (梁仲恒), a resident actor of the Chung Ying Theatre Company¹⁰.

A central conflict comes from money. Because full-time disability sport could not support the family in Hong Kong, So works as a courier and, at his mother's urging, appears in commercials, which drives the two apart; the film's emotional climax is their rupture over the advertising work³^•¹¹. One line of dialogue, in which So says that the government allowance for disabled athletes was only HK$3,000 a month, drew wide online discussion about the lack of support for disabled athletes¹².

The real So Wa-wai

So Wa-wai was born in 1981 in Guangzhou¹³. Jaundice affected his brain at birth, causing spasticity, cerebral palsy, and severe hearing loss¹⁴. His doctors advised his parents against treatment, suggesting they have another, healthy child instead¹⁵. He took his first steps at age four, and throughout kindergarten his mother took him to physical therapy to train his thigh muscles and improve his walking¹⁶.

He began athletics training at 13 and first competed at the Paralympics in 1996, winning gold in the 4×100m relay¹⁷. From age 15 he represented Hong Kong in five Paralympic Games¹⁸. At the 2000 Sydney Paralympics he won three golds and two bronzes, which earned him the nickname "Magic Kid" (神奇小子)¹⁹. From 1996 onward he accumulated 26 gold medals and broke world records five times, taking six Paralympic running golds in total¹⁴^•²⁰. His most memorable race, in his own account, came at the 2008 Beijing Paralympics: after losing his first two events, he won his strongest event, the 200m, and broke the world record¹⁴.

Financial pressure shaped his career. After his father retired early following a work injury in 2002, the family of four lived on the government allowance for disabled athletes and savings; after So won gold at the 2004 Athens Paralympics, So Ma considered asking him to quit running for regular work, until the singer and actor Andy Lau offered him a well-paid job that let him keep training¹³. So retired in 2016, citing a persistent back injury so severe he could not sit through a meal, and later worked with the Hong Kong Sports Association for the Physically Disabled and the Hong Kong Paralympic Committee¹⁸^•²⁰.

Production and release

Jimmy Wan had previously co-written screenplays with Pang Ho-cheung, including Isabella (2006) and Love Off the Cuff (2017), and co-directed shorts and features with Derek Tsang before making Zero to Hero his first solo directorial feature³. Sandra Ng produced the film and played So Ma; the cast also includes Leung Chung-hang, Louis Cheung, and Tony Wu¹⁰^•²¹. So Wa-wai's real-life mother, Hon Siu-ching, joined Wan and Ng in promotion, describing the project as a story about a mother's greatness⁸. Wan said his main purpose in making the film was to remind Hong Kong audiences of So Wa-wai and of other little-known disabled athletes²².

The film premiered in Hong Kong on 12 August 2021 and opened in mainland China on 4 September 2021⁵. Its Hong Kong run was unusually long: 72 days after release, in late October 2021, the film was still in cinemas⁴, Ng had attended some 500 post-screening thank-you events, and the gross was approaching HK$30 million⁶. On 22 October 2021 it was announced as Hong Kong's submission for the 94th Academy Awards⁴.

Reception and awards

On Rotten Tomatoes the film holds a 75% Tomatometer score from four reviews¹. Richard Kuipers of Variety wrote that the film is "kept on course by excellent lead performances"¹. Allan Hunter of Screen International described director Jimmy Wan as serving up "a mountain range of emotional peaks" and noted that the film is not for cynical viewers¹. A South China Morning Post review called it a touching sports comedy⁹, while a Cinema Escapist review characterized its approach as safe and motivational rather than challenging²³. Common Sense Media rated it 3 out of 5, calling it a positive if at times sappy and melodramatic "comeback kid" biopic¹.

At the 40th Hong Kong Film Awards, the film won Best Supporting Actor and received multiple other nominations⁵. It also won an Excellent Film Golden Angel Award and a Best Actress award at the 2021 Chinese American Film Festival⁵. After release, audiences began paying attention to the treatment of disabled athletes in Hong Kong²⁴.

Title

The Chinese title, 妈妈的神奇小子 ("Mom's Magic Kid"), refers to So's media nickname and to his mother. Common Sense Media observed that the English title Zero to Hero reads as implying that someone with disabilities was a "zero" before success, whereas the line "Eyes on your Mom," which So used at the starting line to stay focused, better matches the film's meaning²⁵.
