Jamie Dornan visited 'private sex dungeon' to prepare for 'Fifty Shades od Grey' role

Jamie Dornan has revealed that he paid a visit to a sex dungeon to prepare for his role in Fifty Shades of Grey.

The 32-year-old star, who plays Christian Grey in the adaptation of EL James' erotic novel, said that he visited a private dungeon in someone's home as part of his research, the Mirror reported.

He told ELLE UK he went there and was a beer and they did whatever they were into and that he saw a dominant with two submissives, and he became their kink advisor on the film.

The film, which also stars Dakota Johnson, is expected to release in February 2015.
