A new trailer has been released for the upcoming two-part animated movie adaptation of Batman: The Long Halloween. First published by DC Comics in 13 issues over 1996 and 1997, The Long Halloween is widely considered one of Batman's best and most iconic stories. Check out how it makes the leap to moving pictures in the tense trailer below.

　　Part One of The Long Halloween is expected for a release sometime this summer, with Part Two to follow this fall. No official release dates have yet been announced.

　　The film's recently revealed voice cast includes Batman/Bruce Wayne portrayed by Jensen Ackles, who had previously voiced Jason Todd/Red Hood in 2010's Batman: Under The Red Hood. Joining Ackles are Josh Duhamel as Harvey Dent, Billy Burke as James Gordon, Titus Welliver as Carmine Falcone, David Dastmalchian as Calendar Man, Troy Baker as Joker, Amy Landecker as Barbara Gordon, Julie Nathanson as Gilda Dent, Jack Quaid as Alberto, Fred Tatasciore as Solomon Grundy, and Alastair Duncan as Alfred. Former Glee star Naya Rivera, who died in July last year, completed her voice work as Catwoman/Selina Kyle for The Long Halloween--this will be her last credited role.

　　The Long Halloween always stood on its own as a strong comic and an easy recommendation, and it has only grown in influence and reverence as it famously became the inspiration for Christopher Nolan and The Dark Knight's use of Harvey Dent/Two-Face. So it's no surprise that these comics are also said to be an influence for Matt Reeves' upcoming film The Batman.

　　The official synopsis reads: "Part One begins as a brutal murder on Halloween prompts Gotham's young vigilante, the Batman, to form a pact with the city's only two uncorrupt lawmen (Police Captain James Gordon and District Attorney Harvey Dent) in order to take down The Roman, head of the notorious and powerful Falcone Crime Family." But even before the trio can get a handle on the situation, more deaths occur--suggesting a serial killer may be in Gotham.
