Darnell Lamont Walker

In 2015, Walker had been planning to go backpacking in Europe to celebrate King's Day in Amsterdam, when events concerning the killing of Freddie Gray in nearby Baltimore happened. As he was reconsidering to stay and join in protests, his friend asked "why are you going to Europe? To seek asylum?", inspiring him to repurpose his trip to produce a documentary with the namesake. The film would have man-on-the-street interviews with European locals on what they thought about race relations in the United States and in their own countries.[2] Countries visited included Norway, UK, Netherlands, and France.[11][12] Seeking Asylum had a theater premiere in February 2016 for the Pan African Film Festival.[12] It screened at the Rapid Lion Film Festival in Johannesburg, South Africa,[11][13] and the Virginia Film Festival in Charlottesville.[14][15] It has also screened at other film festivals,[11] and was released online to support the Black Lives Matter movement.[2]

In 2017, Walker released Outside the House, a documentary film on Black mental health. He decided to create the film after a college friend had committed suicide, and when some other friends and associates had over the years.[8][16] In the film, Walker works to "breaking down the barriers and stigmas when it comes to black people discussing their mental-health issues, and confronting the problem head-on". He used social media to call for participants, and would interview them for their stories.[16] Outside the House was screened at multiple film festivals including the Roxbury Film Festival in Boston,[17] as well as special events in places like the DuSable Museum of African American History in Chicago.[18][19] It received an Award of Merit from IndieFEST.[20]

In 2018, Walker completed the film Set Yourself on Fire. The documentary is about rape and sexual assault around the world, with interviews with the survivors.[21] Set Yourself on Fire was screened at the Rapid Lion Film Festival.[22][23] and for the Metro Detroit Association of Black Psychologists.[24][25]

Walker had self-published a children's book titled The Most Beautiful Thing in the World, about a boy who dreams of becoming a pilot, but learns he will be losing his sight.[26] He also wrote I Hate That I Have to Tell You (2016), which is about how to deal with encounters with the police.[27] In 2018, Walker applied to and joined the Sesame Street Writers Room Fellowship.[7][26][4]

Walker joined the Karma's World writing team, writing his first episode in 2019.[28] He wrote the episode "Friendship in a Flash" about Karma making a new friend with dyslexia and her misinformation about the learning disability.[26] He said that the episode aired over two years after he wrote it.[4] In December 2022, he and the show's writing team received a nomination for Outstanding Writing for an Animated Program at the 1st Children's and Family Emmy Awards.[26][29]

Also in 2019, Walker joined the Blue's Clues & You! writing team[26] as a script coordinator.

In 2021, he announced he would be creating an animated short film, Our Song, which is about a boy with ectrodactyly (missing fingers and toes), who wants to play the piano. It is based on a friend's son with the same condition. The project is seeking crowdfunding.[30]

Walker did the teleplay for episodes of Face's Music Party, which aired on the Nick Jr. Channel.

Walker has also worked as a "death doula, writing teacher, creativity coach, and world explorer".[26] This included being a faculty member at the Esalen Institute.[31] In 2015, he started a business called Passport Required, in which he guides tourists from the Black community on a backpacking tour to random parts of the world.[32][33]

He created a narrative installation which resembled a darkroom for Art Gaysel 2022.[34][35]
