In Succession, Brian Cox played Logan Roy to huge critical acclaim for four seasons following the premiere in June of 2018.
The character of Logan is the brash, ruthless owner and leader of a media juggernaut who is more concerned with the future of his business than his relationship with his family, and Cox won the Golden Globe Award for Outstanding Leading Actor in a Drama Series for his portrayal of the mogul.
In what proved to be the biggest shock of the entire series, Logan passed away in episode three of the fourth season. Thereafter, Succession focused on the Roy children - Shiv, Kendall and Roman - and their respective attempts to become CEO of Waystar Royco.
Following Logan's demise, questions were raised not only about who would take over the company, but also with regard to his assets.
But, just how rich was he?
Forbes conducted an investigation into Logan's wealth and determined that he was worth around $18 billion at the time of his death. That number takes into account every single asset including real estate. In terms of cold, hard, cash, Forbes believes he had access to around $1bn when he passed.
Roy owned 36% of Waystar Royco and that figure was key in Forbes' investigation as it is, funnily enough, a similar percentage that Ruper Murdoch has in News Corp. Murdoch is widely believed to be an inspiration for the character.
Roy developed a real estate portfolio worth around $345 million which included a $60m townhouse in New York City and a $10m castle in England which was the venue for Shiv and Tom's wedding.
He is rich enough that he has properties he doesn't even remember buying, such as a $40m beach house in Malibu, California.
In terms of travel, he has $50m worth of helicopters and a $130m superyacht.
Roy's power and wealth are felt throughout the series, so much so that he believes he can even impact policy within the White House.
