Belushi:I guided Frederick Forsythe (Day of the Jackal, 4th Protocol) in Phuket, Thailand
I was not working that day, but we also had Peter Benchley (Jaws author) on our dive boat to fo to one of the southern islands to see the whale sharks.
I did a scuba review for Ewan MacGregor's wife and then guided the pair of them in Langkawi, while he was shooting Rogue Trader.
I had Leonardo DiCaprio and "friend" on my boat while they were filming The Beach. Leo does not dive but his freind did.
