There was controversy about whether Mick Dundee should be considered a crocodile poacher; his use of a rifle to "catch fish" was never fully confirmed in the first movie, Crocodile Dundee (1986). The writers decided to start this film showcasing Mick's extreme measure of fishing, by showing him use dynamite to catch fish in New York harbor. In this way, the writers can safely assert that he was actually fishing, and not a criminal poacher - as he claimed, when he was attacked by a crocodile in the first movie.
Alec Wilson appears in this film as 'Denning', a local Australian hired goon for the drug lords. 13 years later he appeared in the sequel Crocodile Dundee in Los Angeles (2001) as 'Jacko', a long time Australian friend of Mick.
