Actress Emma Watson says she made a music band along with her ‘Perks Of Being A Wallflower’ co-star Logan Lerman on sets of the movie.
The 22-year-old, plays the role of Sam in the movie who is a high school student. The actress says most of the nights both the actors would play music.
"Throughout the movie we all made music together. Our band was called Octopus Jam. I sing and Logan Lerman is a classical composer, and he created a piece for me," a website has quoted Watson as saying.
"Most nights we would sit and play music, so that was fun," she added.
