LONDON (Reuters) - Hedge fund managers are well known for extracting huge fees from their wealthy investors. Relatively few have landed a role in a client's Hollywood blockbuster.

However, Christian Baha, head of $1.2 billon hedge fund group Superfund, has been given a cameo in "Wall Street: Money Never Sleeps," the sequel to the 1987 original "Wall Street," thanks to a friendship with director — and Superfund investor — Oliver Stone.

Baha, whose computer-driven funds aim to exploit trends in global futures markets, has a short speaking role as, perhaps unsurprisingly, a hedge fund manager, while Michael Douglas resumes the role of ruthless financier Gordon Gekko in a film some have seen as a thinly-veiled attack on Goldman Sachs. Baha, a serial entrepreneur who quit a job as a policeman in Vienna in the 1990s to focus on his businesses, now divides his time between Monaco, Vienna and Los Angeles, where he met Stone, a spokesman said. It is likely that the Oscar-winning director of "Platoon" and "Born on the Fourth of July" has experienced a rollercoaster ride.

Superfund's most aggressive 'C' share class gained 74.18 percent in 2008's market chaos, but lost more than 50 percent last year.

In an interview earlier this year Baha told Reuters that investors in long-term trend following funds should expect a year like 2009 "every 20 to 30 years".

So far this year Superfund's 'C' share class is down 9.98 percent after heavy losses in May's market turbulence, although it is still up 267.1 percent since May 2001.

A Superfund spokesman later said Superfund's 'C' share class was not available in the US, and that Stone was invested in the Superfund Gold fund.

This fund, which is denominated in gold rather than in US dollars, gained 20.87 percent last year and 18.5 percent so far this year, helped by a long-running bull market in the yellow metal.
