Work on Shankar's Nanban with Vijay and Ileana was proceeding smoothly when suddenly a glitch was revealed. The team was checking out rushes of the film when it was seen that some of the scenes shot using a particular lens known as S5I were somewhat out of focus. The crew is working on rectifying this.
In the meantime, these lens had been booked for use by the Billa 2 team. When they heard about this slight malfunction, they cancelled the use of S51 at once. Vettai Mannan is another film for which these lenses were employed but fortunately for them, the rushes are looking good and there was no evidence of error.
