Pic, which is based on true events, stars Hanks as Richard Phillips, who allowed himself to be taken hostage by Somali pirates in 2009 in order to guarantee the safety of his crew.
Keener is closing a deal to play Andrea Phillips, who remained strong throughout the hostage ordeal.
Scott Rudin, Michael De Luca, Dana Brunetti and Kevin Spacey are onboard to produce the Billy Ray-scripted pic, which Elizabeth Cantillon will oversee for Sony. All four producers previously worked with the studio on “The Social Network.”
Keener is in for a busy year, as she stars opposite Phillip Seymour Hoffman in “A Late Quartet” and opposite James Franco in the indie “Maladies.” Thesp, who will soon be seen in upcoming releases “The Oranges” and “Peace, Love and Misunderstanding,” also lent her voice to DreamWorks Animation’s “The Croods.”

Keener plans to shoot “Captain Phillips” before she segues to Charlie Kaufman’s musical satire “Frank or Francis.” She is repped by the Gersh Agency.
