Michael Fassbender has admitted he was impressed by British beauty Keira Knightley when they worked together on 'A Dangerous Method'.
The 34-year-old actor plays Swiss psychiatrist Carl Jung, who has an affair with his patient, Russian psychoanalyst Sabina Spielrein (Knightley), in the David Cronenberg directed film and Michael enjoyed shooting scenes with the actress including those where he spanks her.
Speaking at the premiere of the movie at the Odeon West End in London's Leicester Square as part of the 55th BFI London Film Festival on Monday night (24.10.11), he told BANG Showbiz: "[She's] beautiful, amazing, she's very impressive."
Michael also revealed he treated his role in the film - which also stars Viggo Mortensen as Sigmund Freud - like a piece of music, taking time to practise it over and over again.
He said: "I just sort of read The Script and read it over and over and over again, because this script is very dialogue heavy, and that is pretty rare these days in film and so I spent a lot of time with it . it's so articulate, it's got its own rhythm, it's got its own beat so I just treat it as a piece of music and just kept working on it."
Michael was joined at the premiere by co-stars Viggo and Keira, as well as director David and script-writer Christopher Hampton.
