20 Things You Didn't Know About Unbreakable
5. Mr Glass Is Older Than His Mother
In an interesting titbit, the actress who plays Mr Glass/Elijah's mother Charlayne Woodard, is actually a whole five years younger than Samuel L. Jackson himself. Jackson was born in 1948, whereas Woodard was born in 1953.
Woodard appears in the film at several different ages due to the majority of her scenes being flashbacks so perhaps that is why Shyamalan was not too preoccupied with the actors age difference. The actress returned to the franchise in Glass for a brief role, where she was once again made to look older with the help of make-up.
