James McAvoy has praised his Glass co-star Bruce Willis, saying he is the "most chilled dude". For "Glass", M. Night Shyamalan has converged the world of Split (a story about a man, essayed by McAvoy, with over 20 different personalities who kidnaps three teenage girls) and "Unbreakable" (about David Dunn, essayed by Willis, who gets superhero abilities after surviving a train crash).

"Bruce is the most chilled dude. He is so relaxed, but he is bringing such a heaviness to the part," McAvoy said in a statement to IANS.
