- Lupita Nyong'o voices the main character Roz in "The Wild Robot," in theaters Friday.
- Nyong'o strained her vocal cords, forming a polyp while recording Roz's robotic yet emotional voice.
- Recording sessions were halted for three months to allow Nyong'o to recover without surgery.
DreamWorks Animation's new movie, "The Wild Robot," is an emotional story about a utilitarian robot named ROZZUM ("Roz" for short) who finds herself on an island and discovers that her purpose goes far beyond what she was built for.
Voicing a robot who gradually becomes more human also ended up being a physically taxing experience for actor Lupita Nyong'o, who took pains both figuratively and literally to create a voice for Roz that could be both robotic and emotional.
