In 2005 she competed against other contestants on a reality TV show called The Next Movie Star; she was the first runner up. Dikeh's appearance on the show was as a means of getting closer to the "big time", she says, and her start in the Nigerian movie industry came soon after.
Dikeh says that after her second movie Holy Cross, more movie directors and producers were willing to cast her, and she has appeared in scores of movies since. Dikeh's role in the movie Dirty Secret has generated controversy amongst Nigerians, because the movie contains nude scenes. While some criticize her role of being untraditional and un-African, others say that Dikeh is merely being professional.
Tonto was known in Nollywood as a chain smoker and had started smoking since the age of 14 but she recently testified that she stopped smoking after prayers with Pastor T.B. Joshua via his Christian television station Emmanuel TV.
