Gareth Wiley (born 3 March 1962, England) is a film producer, whose professional life started in the world of investment banking, working with County NatWest, Salomon Brothers, and UBS Warburg, moving into film producing in 2002.
Since 2004, he has produced or acted as executive producer on seven feature films, four of which have been with Woody Allen, having persuaded Allen to move his 2004 movie to London. In January 2009, Wiley won a Best Picture Golden Globe for Allen's "Vicky Cristina Barcelona". This was Gareth's second Golden Globe nomination in four years, having been previously nominated in 2006 for his first collaboration with Allen, "Match Point".
Wiley studied business with economics and law, before starting his working life as a banker in February 1985. Involvement in film finance and production began as early as 1993. Prior to working with Woody Allen, he maintained a career in investment banking (working in London, Hong Kong and the United States) in parallel with an increasing involvement in film finance and in 2002 committed himself to working exclusively in film and other creative businesses.
