CHICAGO (CBS) The brother of the director of "The Dark Knight" was apparently planning his own Batman-style escape from the Metropolitan Correctional Center, according to CBS station WBBM.

Matthew Nolan, the brother of "The Dark Knight" director Christopher Nolan, is being held at the prison, accused of a murder in Costa Rica.

Authorities say he was planning to bust out of his cell and scale down the side of the building. The Chicago Tribune reported that Nolan had a rope made from bed sheets, a harness, a razor, and a metal clip to unlock handcuffs.

Matthew Nolan is charged in Costa Rica with the 2005 murder of Florida accountant Robert Cohen. A U.S. federal judge found there is no evidence directly linking Nolen to the killing, but said he can still be extradited to Costa Rica on charges of using a phony British passport, the Tribune reported.
