In 1995, Canadian director James Cameron chartered the Akademik Mstislav Keldysh and the MIRs to make 12 dives to Titanic. He used the footage in his blockbuster 1997 film Titanic.[61] The discovery of the wreck and a National Geographic documentary of Ballard's 1986 expedition had inspired him to write a synopsis in 1987 of what eventually became the film: "Do story with bookends of present day scene of wreck using submersibles intercut with memories of a survivor and re-created scenes of the night of the sinking. A crucible of human values under stress."[62]
