She has also written and produced several short films. Anadu's films are known for tackling issues of gender discrimination and cultural pressures surrounding tradition in Nigeria. Her first short film, Epilogue (2009), was shown at the 2010 San Diego Black Film Festival in the United States. Ava (2010) was shown in the Cannes Film Festival's Short Film Corner in 2010. Anadu applied to the Cannes Cinéfondation Residence Program in Paris. The 14-page screenplay treatment that was part of her submission was the basis for what would become her first feature-length film, B for Boy (2013). Anadu secured one of the six spots and moved to Paris to take part. She wrote the screenplay for B for Boy (2013) during her two-and-a-half-week stay.
