Adapting the award-winning DC Comics miniseries DC: THE NEW FRONTIER by Darwyn Cooke, Justice League: The New Frontier spins a tale of the DC Universe in the 1950s, focusing on test pilot Hal Jordan (Green Lantern) and the Martian Manhunter. The story also features other DC characters, including Barry Allen (the Flash), Superman, Wonder Woman, Batman, and many more. Written by Andrew Laubacher
This is a fantastic film, retaining the style and flavour of the original tale, and for me bringing back a real sense of the earliest Justice League stories and the original heroes of the DC Silver Age.
Reading some of the other reviewers they seem to want the glitzy shiny polished versions that have been popularised these days, but I've got to be honest - these stocky built characters beat out the ballet dancer heroes of today in my book. And the feel of Jack Kirby through especially the latter part of the film.
The story itself does a great job of integrating the Golden Age Justice Society days and the Silver Age Justice League days. A worthy piece of work, and I hope we see more of these special projects from the Warner animation department (and Bruce Timm!)
