Marlon Brando reportedly wanted to voice a dolphin in the 1996 family film *The Island of Dr Moreau*, despite being cast as the film’s human antagonist, Dr Moreau. The anecdote illustrates the actor’s increasingly unconventional approach during a notoriously troubled production and his willingness to pursue eccentric creative ideas.

The article title refers to Brando’s interest in playing the voice of a dolphin, apparently responding to concerns about the idea by saying, “Don’t worry about it”. *The Island of Dr Moreau*, adapted from H. G. Wells’s novel, became known for production difficulties, including director changes and disputes between cast members.
