According to ComicBook.com on Feb. 5, a recent release of a Japanese TV spot for "X-Men: Days of Future Past" became available online. It basically has the same scenes of action and drama as in the previous trailer followed by the same music, too. There is some Japanese lettering visible as well.
Some of the scenes include Logan preparing to travel back in time to a period to where he would encounter the previous cast. Storm is also scene engaging in her powers as well as Colossus making a run for it.
Some time ago, there was a quick tease or flash of scenes thrown together and tweeted by Bryan Singer. Also, Singer is slated to work on the sequel "X-Men: Apocalypse". For those who don't know which villain that is, he's basically the world's oldest mutant with powers that pretty much overwhelms many who oppose him. There was a rumor going around about an end tease which entailed Magneto's encounter with Apocalypse, but was dismissed by Singer.
"X-Men: Days of Future Past" is scheduled to be released in theaters on May 23.
