What is the name of the lawyer representing Hammond's investors in Jurassic Park?

The lawyer representing Hammond’s investors in Jurassic Park is Donald Gennaro.

Gennaro is sent to investigate whether John Hammond’s dinosaur park is safe after serious incidents raise concerns among the investors. He brings Ian Malcolm into the inspection group, while Hammond invites Alan Grant and Ellie Sattler to assess the park’s scientific and operational risks.

In the 1993 film, Gennaro is played by Martin Ferrero. He initially focuses on the park’s financial potential, but fear takes over when the security systems fail. He abandons Lex and Tim near the Tyrannosaurus paddock, hides in a toilet, and is killed when the escaped Tyrannosaurus finds him.

The character differs from the novel, where Gennaro is more capable and survives the island’s events. The film also combines some elements of other characters from the book. Peter Ludlow belongs primarily to The Lost World, Nick Van Owen is another character from that sequel, and Lewis Dodgson is associated with InGen’s rival corporation rather than Hammond’s investors.
