My first impression from this trailer is that Peter Jackson and director Amy Berg‘s West of Memphis, a doc that will screen at Sundance 2012, is slicker and artier looking than Joe Berlinger and Bruce Sinofsky‘s three docs on the exact same Arkansas-murder-case subject. Which indicates than West of Memphis has more money behind it. Which isn’t surprising with Jackson producing.

Berlinger and Sinofsky docs are titled Paradise Lost: The Murders at Robin Hood Hills (’96), Paradise Lost 2: Revelations (’00) and Paradise Lost 3: Purgatory (playing this month on HBO). They’re all about the wrongly convicted Damien Echols, Jason Baldwin and Jessie Misskelley Jr., a.k.a., the “West Memphis Three”, who were convicted of the 1994 murders of three 8-year-old boys in West Memphis, Arkansas.
