"Getting to see Karan Johar's 'Student of the Year' at night has been refreshing and filled with joy... the young talent, the enthusiasm and vigour in their application, their faultless performances and the deft touch of a director who knows his craft backwards," Big B wrote on his blog, post a trial of the film here Wednesday night.

'SOTY' marks the Bollywood debut of actors Varun Dhawan, Siddharth Malhotra and Alia Bhatt. Amitabh, whose last big screen outing was the 2011 movie 'Bbuddah... Hoga Terra Baap', has expressed his wish to work with an energetic cast and be part of the new talent.

"A desire creeps in of being at their age again and to get opportunity to work along with them, to share their youthful exuberance and freedom, their ability to bring light. Each attempt made by this generation fills me with happiness and joy," he wrote. 'SOTY' releases Friday.
