It's a UK magazine. River was briefly featured in an article entitled "Young, gifted and... dead", listing talented people who died before the age of 30. Other "nominees" include Thomas Chatterton, Tutankhamon, James Dean, Keats and Nick Drake.

River Phoenix's father was originally called John Bottom before joing the Children of God cult, undergoing the name change and becoming the self-styled "Bishop of Venezuela". The child actor, who died outside Johnny Depp's Viper Room nightclub, was christened River Bottom.
