Currently portraying two-dimensional archaeological protectress Lara Croft in Paramount’s “Tomb Raider,” Angelina Jolie is now aiming to do something for the living. The thesp, who won the supporting actress Oscar for her perf in “Girl, Interrupted” last year, is in negotiations to take on the leading female role opposite Kevin Costner in Oliver Stone’s “Beyond Borders.” Pic is being financed by the Par-based Mandalay Pictures.According to insiders, Jolie was drawn to the high-minded material of the international relief worker-themed romantic drama (the group to which its protagonist belongs bears a striking resemblance to Doctors Without Borders, which won the 1999 Nobel Peace Prize) and she is said to be quite enthused at the prospect of working with Stone and Costner. Casting of the role for which Jolie is in talks has been beset by several false starts. One-time co-star Catherine Zeta-Jones dropped out of the role due to her pregnancy, and, after several months of serious negotiations, talks with Meg Ryan have stalled. Jolie most recently starred opposite Nicolas Cage and Giovanni Ribisi in the Mouse’s “Gone in Sixty Seconds,” and will star opposite Antonio Banderas in Michael Cristofer’s “Original Sin” for MGM. Jolie is managed by Industry Entertainment’s Geyer Kosinski and repped by her attorney Robert Offer at Bloom, Hergott, Diemer & Cook.
