Peter Dinklage Nicola Peltz Split - H 2015

And nabbing a leading role in a competitive situation is 'Transformers: Age of Extinction' actress Nicola Peltz, who is also in negotiations to join the cast of Fox's adaptation of the John D. MacDonald mystery book.

Game of Thrones star Peter Dinklage and Transformers: Age of Extinction actress Nicola Peltz are in negotiations to join Christian Bale and Rosamund Pike in Deep Blue Goodbye, Fox's adaptation of the John D. MacDonald mystery-adventure books.

James Mangold is directing the project, which was at times operating under the title Travis McGee. McGee is the protagonist of the picture. He's a free-wheeling bachelor living on a house boat, acting as a self-proclaimed "salvage consultant."

The script sees McGee, now reimagined as an Afghan war vet, on the trail of stolen sapphires, which leads to a sadistic torturer.

Dinklage will play a mathematician who made a fortune thanks to an app and ends up as McGee's sidekick.

Peltz, in a potentially career breakthrough role, will play a woman who acts older than she is, knows more about the sapphires than she lets on, hires McGee to find them and ends up on the wrong side of the torturer.

The movie is looking at a May start, shooting in Puerto Rico and Florida. Chernin Entertainment is producing along with Appian Way and Amy Robinson.

Dinklage appeared in last summer's Fox franchise X-Men: Days of Future Past and will be seen this summer in Sony's Pixels opposite Adam Sandler and Josh Gad. He was recently cast in the Melissa McCarthy comedy Michelle Darnell. HBO's Thrones, for which the actor has won an Emmy and a Golden Globe, returns April 12. He is repped by CAA, David Ginsberg of Insight and Jackoway Tyerman.

Peltz, repped by WME and Management 360, was the female lead in last summer's Age of Extinction and now recurs on A&E's Bates Motel. She was just cast in Universal's Untitled Low Riders Movie, which she will shoot after Deep Blue Goodbye.
