As the film went into pre-production, and Weir was in Central America scouting for locations, the financial backing for the film fell through and the project was suspended indefinitely. In the meantime, Weir was approached to direct "Witness" starring Harrison Ford. The film, which was Weir's first American production, was a critical and commercial success, garnering eight Academy Award nominations including Weir for Best Director, Ford for Best Actor, and the film itself for Best Film. During the production of "Witness", Weir discussed "The Mosquito Coast" with Ford who became interested in the role of Allie Fox (though Ford's agent was less enthusiastic). With Ford attached to the project, financial backing and distribution for the film was easier to find (ultimately from Saul Zaentz and Warner Bros.).
