The actor-producer-writer, who turns 49 next month, has three interesting projects currently in development as a performer.

One is TV series The Mosquito Coast, which is an adaptation of Justin’s uncle Paul Theroux’s famed novel of the same name.

The Mosquito Coast was previously adapted into a 1986 film, starring Harrison Ford, Helen Mirren and River Phoenix.

The story revolves around an idealist (to be played by Justin) who uproots his family and moves them to Latin America to create a new utopia.
