Manic is a 2017 Canadian documentary film directed by Kalina Bertin. The film depicts Bertin's efforts, in response to a family history of bipolar disorder, to investigate parts of her father's prior life in Montserrat that she did not know about; she ultimately uncovers the revelations that her father was a cult leader who also suffered from bipolar disorder, and who had, unbeknownst to Bertin until making the film, also fathered at least 12 other children with four other women.

The film premiered at the 2017 Hot Docs Canadian International Documentary Festival.
