Director M. Night Shyamalan has said his next film will be a sequel to two of his movies, Split and Unbreakable.

Glass will see Bruce Willis and Samuel L. Jackson reprise theirs roles from Unbreakable, while James McAvoy and Anya Taylor-Joy will return to their roles from Split and see the two films "collide" in a super sequel.

Shyamalan, who broke through with the massive success of The Sixth Sense in 1999, announced the news in a string of tweets, in which he said: "Okay. Here we go. Finished the new script.

"My new film is the sequel to #Unbreakable AND #Split. It was always my dream to have both films collide in this third film," he said in Twitter-speak.

"The virtuoso #JamesMcAvoy returns as Kevin Wendell Crumb, Patricia, Dennis, Hedwig, Barry, Jade, Orwell, The Beast, Heinrich, Norma, and Pol.

"And the prodigy, @AnyaTaylorJoy will return as Casey Cooke."

The director confirmed he would be re-teaming with Universal Pictures and producer Jason Blum for the "crazy comic book thriller", adding: "Universal Pictures will release #Glass on January 18, 2019 all over the world. How's that for not keeping a secret!"

The film will follow on from the end of Split, which stars McAvoy as a man with 23 personalities who kidnaps and imprisons three girls.

In August 2015, Shyamalan was in Dublin to promote his film The Visit.
