According to wealth estimation site Celebrity Net Worth, Ivan Reitman’s net worth at the time of his death was as high as $100 million. While there’s likely a fair bit of guesstimation in this figure, it’s definitely easy to believe that Reitman’s finances might be roughly in this ballpark. After all, he directed numerous box office hits in the 1980s and 1990s — for reference, the Arnold Schwarzenegger-Danny DeVito comedy “Twins” alone earned nearly $112 million worldwide against a $15 million budget, per Box Office Mojo.
Still, Reitman’s most lucrative job was quite likely producing. He amassed dozens of producer credits over the decades, to the point that he’s listed as a producer in a number of works that are still in pre-production stage. He produced many of his own successful films, including every live-action “Ghostbusters” movie. Among his other producer credits are the 1996 basketball adventure comedy “Space Jam” and its 2021 sequel, as well as Jason Reitman’s George Clooney-starring award season darling “Up in the Air,” which made $166 million internationally against a $25 million budget (via Box Office Mojo).
