Blake Lively is in negotiations to star in Sony’s shark movie “In the Deep,” which has been described as a cross between “127 Hours” and “Jaws,” multiple individuals familiar with the project have told TheWrap.

Jaume Collet-Serra (“Run All Night”) recently came on to replace Louis Leterrier as director. He’ll be working from a script by Tony Jaswinski that Sony acquired in a bidding war last fall.

“In the Deep” will pit Lively against a sadistic shark that has her trapped on a buoy 20 yards from the shore. The script is said to provide a strong emotional vehicle for a young actress, and Lively is a solid fit for the material.
