"True Blood" star Sam Trammell is set to play Shailene Woodley's father in Fox's "The Fault in Our Stars," TheWrap has learned.

Josh Boone ("Stuck In Love") is directing the adaptation of John Green's bestselling novel.

Story follows two cancer-stricken teens who strike up a romantic relationship as they face an uncertain future.

Ansel Elgort, who plays Woodley's brother in "Divergent," co-stars as her love interest Augustus, while Nat Wolff has just closed a deal to play his best friend Isaac.

Trammell is the second HBO-approved star to be cast as Woodley's parent, as Laura Dern ("Enlightened") is set to play Woodley's mother, as TheWrap first reported.

"Twilight" producers Wyck Godfrey and Marty Bowen are producing through their Temple Hill banner. "(500) Days of Summer" screenwriters Scott Neustadter and Michael Weber adapted the novel.
