Dubliner and Trinity College graduate Sir William Sargent is the CEO and co-founder of Framestore, a London-headquartered Oscar and Emmy-award winning creative and visual effects studio that employs 800 people, with offices in LA, Montreal and New York. Founded in 1986, among the movies it's worked on are Gravity, Avatar, Harry Potter spin-off Fantastic Beasts and all the recent Marvel superhero ones, to name just a few.
Last November, Chinese investment firm Cultural Investment Holdings bought 75pc of the business in a deal that valued it at 175m, and one of its new directors is the 80s and 90s martial arts movie star Jackie Chan.
Sargent — who worked as a Galway barman and a radio DJ in his youth — is believed to have retained a 10pc stake in the firm. A 30pc stake had been sold in 2014 to a group backed by Malaysia's sovereign wealth fund for about 15m at a lower valuation.
