Sarah Paulson discusses which 'Glass' actor has the biggest 'delusion of their grandeur' IRL

Acting in a big budget Hollywood movie means you're likely to be surrounded by some pretty big personalities.

Just ask Sarah Paulson. Not only is she a very big character herself, but she just starred in M. Night Shyamalan's Glass alongside Bruce Willison, Samuel L. Jackson and James McAvoy.

And the question Stephen Colbert wants to know in The Late Show clip above, is: Who has the biggest delusion of their own grandeur in real life?

"You know, it's Hollywood," says Paulson. "Everybody's gotta kinda like... it's par for the course.

"I will say Sam Jackson — it's not a delusion of grandeur — he's just the coolest cat around. And he takes about 10 minutes to walk, like, two feet.

"And you just wait for him to do it, because it's Sam Jackson."

Makes sense.
