Atman Simbu left his fans captivated and confused by sharing a short video. Fans believed that it had something to do with his upcoming film 'STR 48', directed by Desingh Periasamy. This movie is said to be a period action film and the short video was set in a historical backdrop.

However, a few were convinced that it was an advertisement video. The latest is that Simbu is the new brand ambassador of the residential building brand, Casa Grand. We hear that the teaser released by STR was a prelude to the ad film that Simbu has done for Casa Grand Sun City. This news disappointed the fans of the actor.

The BTS pictures from Simbu's ad film shoot are also out and doing rounds on social media. On the other hand, 'STR 48' is produced by Kamal Haasan. The film's first look featuring STR's dual roles was unveiled earlier this month. The shooting is expected to begin in March and the fans are eagerly waiting for an update.
