Akkineni Naga Chaitanya's upcoming romantic entertainer 'oka laila kosam's theatrical trailer was unveiled by the makers on the evening of 12th August. Like many of the previous romantic entertainers, 'oka laila kosam' also appeared to have been made based on the ego clashes of the leading actors. Very first dialogue of the trailer tickles your funny bones and it goes on,  " NUVVU NAA HUSBAND AITHEY..SOBHANAM ROJE PALALLO VISHAM KALIPESHT", says heroine. In retort, hero says, " NUVVU NAA PELLAM AITHEY AA PALU THAGI CHASTHAA,". 

However, the love story appears to be the hate story, as the heroine continues to hate hero till the end of the trailer. As such, it would be interesting to see how the heroine woos the hero, as it was not shown in the trailer. On a whole, the 'Gunde Jaari Gallanthayyinde' director, Vijay Kumar Konda, has been succeeded in generating the curiosity among the audiences who like to watch romantic films. Though the background score of Anup Rubens was partly ok, it cannot be assessed with just 1.42 minutes of the trailer. Pooja Hegde looked average in this trailer.
