Pollock's last performance was in the 1992 film Romper Stomper alongside New Zealand actor Russell Crowe.
On 13 April 1992, 23-year-old Pollock, battling depression and fearing a prison sentence in an upcoming court case, committed suicide[1] by walking in front of a train at Newtown railway station, Sydney, prior to the release of Romper Stomper.
His Romper Stomper star Russell Crowe wrote a song in 2001 called "The Night That Davey Hit the Train" about his death.
