Hollywood actor Armie Hammer has admitted he felt "apprehensive" while shooting nude and intimate scenes in 'Call Me By Your Name'. The 31-year-old actor plays the role of Oliver in the coming-of-age drama 'Call Me By Your Name' and throughout the movie - which was helmed by Luca Guadagnino - the star had to do multiple nude and sexual scenes, which he admitted left him feeling less than confident at first.
