Big Bud Dean

Big Bud Dean is a major character in the 1988 film, Heathers and is portrayed by Kirk Scott. He is the father of J.D. and the owner of Big Bud Dean Construction. Big Bud jokes that the company is more of a “deconstruction” company, since most of the company's work is about blowing up buildings.

Mrs. Dean
Not much is known on the specifics of Big Bud and his wife's relationship, but his wife killed herself using his work. She killed herself by walking into a library just minutes before Big Bud hit the switch to blow it up during their time in Texas. Her suicide heavily affects his relationship with his son.

J.D.
His relationship with J.D. seems to be strained after the death of J.D.'s mother. Their relationship is a joking switch of roles. Big Bud will make jokes like "gosh, pop, I almost forgot to introduce my girlfriend" and J.D.'s response will be "son, why don't you ask your little friend to stay for dinner?".

J.D gets the idea of the bomb to blow up Westerburg High School when watching one of Big Bud's demolition videos. Big Bud is telling J.D. about how he had put a Norwegian bomb in the boiler room, which set off the thermals in the floors above. From there, J.D. builds the bombs to blow up the school.
