For someone who made films that defined a generation, Ivan Reitman is not a household name.
His legacy lies in the shouts of "toga" at university parties, children dressed in jumpsuits at Halloween, a dunkin' Bugs Bunny and Arnold Schwarzenegger's meme-worthy deliver of "it's not a tumour".
The director and producer died peacefully in his sleep on Saturday aged 75.
Here are some of his greatest works.
National Lampoon's Animal House (1979)
Reitman's big break came from working as a producer on one of the most influential comedies of the 1970s.
The raucous, college fraternity send-up Animal House, starring Saturday Night Live comedian John Belushi, was a box office hit.
In 2001, the Library of Congress added it to the National Film Registry, which is a selection of films deemed "culturally, historically or aesthetically significant" to America.
Its legacy extends to the popularity of toga parties, food fights, quotable lines and one of Belushi's greatest performances before his untimely death just four years later.

Ghostbusters (1984)
Who you gonna call?
When actor and comedian Dan Aykroyd wrote the script for Ghostbusters, he picked Reitman to direct what would be a defining movie of the 1980s.
Ghostbusters launched a million Halloween costumes, a successful four-movie franchise and remains one of the greatest comedy films of all time.
Reitman returned to direct the 1989 sequel Ghostbusters 2 and worked as a producer on the 2016 female-led reboot Ghostbusters: Answer the Call.
He was also a producer on the recently released third instalment of the original series, Ghostbusters: Afterlife, which was directed by his son Jason Reitman.
The pair worked together on the 2009 George Clooney film Up in the Air, which was nominated for six Oscars including Best Picture.
Twins (1988)
Before Twins, Arnold Schwarzenegger was the big-armed action man in roles like Hercules, Conan, the Terminator and Predator's Dutch.
Reitman paired him on screen with Danny DeVito as a long-lost twin brother, and Schwarzenegger's era of comedy was born.
Twins was a box office hit, and reportedly DeVito and Schwarzenegger's biggest earner as they both chose to forgo a salary in exchange for a share of the film's earnings.
Schwarzenegger would go on to work on the next three films Reitman directed: Kindergarten Cop (1990), Dave (1993) and Junior (1994).
Reitman, Schwarzenegger and DeVito were reported to be shooting the sequel to Twins in Boston last month called Triplets, starring Tracey Morgan as the third long-lost sibling.
Space Jam (1996)
On paper, it was terrible: Michael Jordan on the verge of a comeback teams up with Bugs Bunny and the Looney Tunes to fight aliens in the ultimate basketball game.
But on screen, it was a rare kind of magic that remains special to people born in the 1990s.
The movie was based on a 1992 Super Bowl commercial that director Joe Pytka did with Bugs and Jordan to promote Nike's Air Jordan sneakers.
As one of the film's producers, Reitman helped bring all of the elements together to make Space Jam an iconic movie.
He was also responsible for the cameo by Bill Murray, who appeared in the animated showdown because "the producer is a friend of mine".
Before Ghostbusters and its sequel, Reitman had directed Murray's first credited film, Meatballs, in 1979 and reunited with him for the 1981 war comedy Stripes.
Reitman's daughter Catherine Reitman, who created and stars in the TV series Workin' Moms, also voiced the purple Monstar, Nerdluck Bupkus.
While Space Jam has remained a childhood favourite since its release in 1996, the 2021 reboot Space Jam: A New Legacy was panned as a shameless cash grab.
