Toho has just released the first full length trailer for the upcoming live-action adaptation of Isayama Hajime’s cult hit manga Attack On Titans ( Shingeki No Kyojin ), offering a few glimpses of the Colossal Titan :

The first film is set for released ( in Japan ) on the 1st of August 2015 and the 2nd part on the 19th of September. Official site here.

For those who might be new to the franchise I also recommend the anime series, which feature some pretty intense and impressive sakuga sequences.
