The suspense thriller "Let Him Go" has added two big-name stars: Kevin Costner and Diane Lane.

The upcoming film from director Thomas Bezucha will star the two as a married couple on a mission to save their grandson, THR reports. The story is based on Larry Watson's novel of the same name. Bezucha penned the script.

Like the novel, the film centers on the George (Costner) and Margaret Blackledge (Lane), a couple who loses their grandson when his mother remarries and moves away. With the boy being raised among his stepfather's dangerous family, the Blackledges decide they have to get him back. Conflict arises when the Weboys are unwilling to let the Blackledges take him.

Both Costner and Lane continue to have prolific acting careers. He has starred in a number of high-profile films, such as 2016's "Hidden Figures," 1992's "The Bodyguard," and 1987's "The Untouchables." Meanwhile, Lane's credits include the likes of 2015's "Trumbo," 2003's "Under the Tuscan Sun," and 1983's "The Outsiders."

Production on "Let Him Go" is scheduled to begin this spring. Rod Lake is set to executive produce, while Mazur Kaplan's Paula Mazur and Mitchell Kaplan, Bezucha, Costner, Kimi Armstrong Stein, and Jeffrey Lampert will produce. Josh McLaughlin is overseeing.
