I guess Jake saw those pictures of Hugh Jackman at the beach this morning too because he up and signed on to be in a movie with Hugh today, he did! Via The Playlist:
"Gyllenhaal will join Hugh Jackman and the recently announced Melissa Leo in "Prisoners." The Black List script penned by Aaron Guzikowski (“Contraband”), revolves around a small-town carpenter named Keller (Jackman) whose young daughter and best friend are kidnapped. After the cops fail to find them, Keller takes the law into his own hands, but in the process runs up against the big city detective assigned to the case. No word yet on Gyllenhaal's role, but apparently a script polish convinced him to enter talks."
Right - it was a script "polish" that did it. I'm sure Jake polished off something, anyway...
