McAvoy, Willis, Jackson premiere new Shyamalan sequel, 'Glass'

Nineteen years after his superhero thriller "Unbreakable" hit theaters, director M. Night Shyamalan has delivered the final installment in his Eastrail 177 Trilogy– "Glass."

It sees "Unbreakable" stars Bruce Willis and Samuel L. Jackson reprise the roles of David Dunn/The Overseer and Elijah Price/Mr. Glass respectively – two individuals, one good, one bad, with superhuman strength, intelligence and perception.

Joining them in "Glass": James McAvoy and Anya Taylor-Joy, stars of Shyamalan's 2016 feature "Split" – about a man with 23 different personalities who kidnaps three teenage girls and locks them in an underground prison.

On Wednesday (9 JANUARY 2019), Shyamalan and the actors flew into London to premiere the movie, on a bright white carpet lined with fans eager to see the conclusion to the director's story.

McAvoy says preparing to play the role of Kevin Wendell Crumb/The Horde was tough.

The actor embarked on a grueling workout regime, reportedly eating up to 6,000 calories a day to get buff.

"I got vascular. I got real vascular, We had some tricks though for making my veins pop and also we've got CGI helping out there too, but I was truly veiny."

"Glass" smashes into U.S. and U.K. theaters January 18.
