Watch the Inspiring Trailer for Chiwetel Ejiofor’s ‘The Boy Who Harnessed the Wind’

“It’s not a dream, Papa,” insists young William Kamkwamba, played by newcomer Maxwell Simba in this new trailer for Netflix’s The Boy Who Harnessed the Wind. “I’m not dreaming.”

And indeed he isn’t – and wasn’t. Based on a true story, the film, directed by and starring Chiwetel Ejiofor, chronicles the very real hopes and efforts of a 13-year-old William in Malawi as he develops a method – the wind of the title – to bring water to his famine-struck village.

Based on the book of the same title written by Kamkwamba and Bryan Mealer, The Boy Who Harnessed the Wind marks Ejiofor’s directorial debut (he also wrote the adaptation of the book).

In addition to Ejiofor and Simba, the film features Aïssa Maïga and Lily Banda. Producers are Andrea Calderwood and Gail Egan.

The Boy Who Harnessed the Wind debuts March 1 on Netflix and in select theaters. Check out the trailer above.
