William Hurt travels The River Why

Matt Leutwyler’s busy notching up the actors to appear in the adaptation of David James Duncan’s novel The River Why.

It’s a coming-of-age tale that finds obsessed fisherman Gus (Zach Gilford) endlessly searching for an elusive rainbow trout which – metaphor alert! – stands in for his quest for self-knowledge.

Now William Hurt has joined the film as his father, while Amber Heard will play Gus’ love interest, a headstrong, tomboy fly-fisher.

The Hollywood Reporter is looking for its waders .
