William Hurt and Amber Heard have boarded Matt Leutwyler’s upcoming coming-of-age drama “The River Why,” according to The Hollywood Reporter.

Based on David James Duncan’s 1983 Sierra Club novel, the movie focuses on Gus Orviston (played by Zach Gilford), a young man who embarks on a quest to find an elusive steelhead trout. In fact, his search for the fish is a metaphor for his search for self-knowledge.

Hurt plays Gus’ father, while Heard jumps into the role of his love interest, an adventurous fly-fisher. Leutwyker is directing an adaptation by Thomas A. Cohen and John Jay Osborn Jr.

Heard recently starred in Jeff Wadlow’s action flick “Never Back Down.” She will next be seen alongside Seth Rogen and James Franco in David Gordon Green’s “Pineapple Express.”

Hurt is currently onscreen in Universal’s “The Incredible Hulk.” He recently wrapped principal photography for Julie Delpy’s upcoming drama “The Countess.”
