  Because of his limited appearances, fans have debated if Broly can be considered part of the larger Dragon Ball canon for years. But in a note on the Dragon Ball Super: Broly website, series creator Akira Toriyama said he worked to fit Broly into the Dragon Ball universe.


Hopefully that links confirms that Broly is canon now. The movie basically retcons Broly's origin. That's why his father looks older and different than in the DBZ Movie.
