Ivan Reitman: Afterlife

He even grand-marshalled the Christmas Rose Parade in Pasadena, California.  That tells he was one of the most beloved movie makers there was.  Ian Reitman's best directing works must be "Ghostbusters", "Animal House", but a superb romantic comedy such as "Legal Eagles" starring Robert Redford also was outstanding.

Essentially a comedy person, in 1975 he produced a off-Broadway 'National Lampoon Show' with Bill Murray, very much the base, beginning, of the entertainment, he wanted to present.

The father, did attend the premiere of "Ghostbusters: Afterlife (2021)".  The legacy well inherited to his son, the director, Jason.
