Brian Madison was Billy Madison’s dad in the movie. Kind of bland for a character, but I can’t exactly hate him.

He was the founder of a hotel chain that was very successful and made him extremely rich. But he was not the greatest father as he let Billy grow up to be this man-child in which he kind of makes the problem worse by even allowing him to have this contest of going through school again.

But he did love his son and did support him when he actually was trying.
