Dhanush once thought Mammootty was 'rude', changed his mind

At the pre-release event of upcoming spy thriller OM, Dhanush revealed he initially found Mammootty 'rude' after a brief interaction during the 2013 Malayalam film Kammath & Kammath. After working with him again, Dhanush said he realised within three days that Mammootty is "sweet, humble, grounded and giving" with an "unbelievable" sense of humour.
