Dubbed the 'president of cinema', he co-founded DreamWorks SKG in 1994 and is worth £1.1 billion.
How did he make his millions? Apparently, the young Spielberg got noticed by donning a suit and occupying an empty office on the Universal lot, letting staff think he belonged there. Jaws took £143 million, heralding a string of hits that brought in £3 billion worldwide. He takes a big share of his films' gross, including income from rentals, TV rights and merchandise - Jurassic Park is said to have made him £162 million. Then there are the receipts from DreamWorks and Universal's theme parks; the planned IPO of DreamWorks Animation is expected to raise $650 million.
What's the secret to his success? His endless ideas and emphatic work ethic are underwritten by a shrewd business sense.
