screenplay by Daniel James and John Carney
directed by John Carney
by Walter Chaw John Carney's On The Edge is sort of a Gaelic One Flew Over the Cuckoo's Nest: an irreverent teen Murphy ("Cillian Murphy" as it happens, playing a character named Jonathan Breech) inspires a batch of ruined adolescents in a County Dublin asylum to restore themselves through the healing power of petty rebellion. It's formulaic and derivative at the least, but the soundtrack, performances, and smooth look of the piece elevate its stagnant material into something--at least fitfully--emotionally engaging, if not intellectually involving.
