Although a trailer is still some way out, the first poster for 'Glass' has gone online and already kicked off the hype-train for M. Night Shyamalan's long-awaited sequel to 'Unbreakable'.

It's a pretty slick-looking trailer, showing Mr. Glass (Samuel L. Jackson), The Horde (James McAvoy) and David Dunn (Bruce Willis) and a reflection of their personas on the ground. There's no word yet on specifically what the plot is, beyond it reuniting the cast of 'Unbreakable' and 'Split'.

Director M. Night Shyamalan tweeted out the poster from his personal account earlier today, with the tease that the trailer for 'Glass' is likely to drop at the San Diego Comic Con on July 20th.

The movie will land in Irish cinemas on January 18th.
