Kalki Koechlin, who was previously married to filmmaker Anurag Kashyap, says marriage was the most innocent thing she has done so far. She feels for a successful married life one needs a lot of "trust" and "innocence".

Kalki, who awaits the release of 'Waiting', appeared on TV show 'Yaar Mera Superstar' alongside veteran actor Naseeruddin Shah to promote their forthcoming film.

When asked what is the most 'Masoom' (innocent) thing she has done so far, Kalki said: "Get married. I think it's a pretty huge trust in somebody else, you know, getting married. I think it's like pretty, you need a lot of innocence to believe in marriage."

'Waiting' is about the relationship between two people from different walks of life, who befriend each other in a hospital, while nursing their respective comatose spouses. The story of the film divulges into the themes of coping with grief and discovering hope.

The film is set to release on Friday.
