Armie Hammer went on an "emotional journey" working with director Luca Guadagnino on 'Call Me By Your Name'. The 31-year-old actor plays the role of Oliver in the romantic coming-of-age drama and admitted the passion that Guadagnino showed on set and his openness to the cast's ideas was a completely new experience for him. The feeling of operating from that place of passion is really contagious and soul-satiating.
