In 1995, production began on the film when Cameron shot footage of the actual Titanic wreck. The modern scenes were shot on board the Akademik Mstislav Keldysh, which Cameron used as a base while filming the actual wreck. A reconstruction of the Titanic was built in Baja, California, at Playas de Rosarito. Scale models and CGI effects were also used to create a more realistic version of the ship.
