We saw Aamir Khan sporting a transistor for the first poster of P.K., which created a huge buzz around the movie. (leave alone the controversy)
Ranveer Singh is seen holding the transistor in the song Sweeta from his upcoming film Kill Dil. The transistor goes perfectly with the theme of the song.
Shahid Kapoor on the other hand is holding the transistor while delivering a monologue in Haider which is a crucial point in the film.
The transistor has officially made a comeback in Bollywood films as a prop.
