Gracy’s soft and endearing personality went in her favor and she became the part of the film that created history.

The year 2003 marked the release of three of her films ‘Armaan’, ‘Gangajaal’ and ‘Munna Bhai MBBS’. MBBS was another super hit film. Gracy turned out to be the actress with best ratio of hits to her credit.

With a few successful films under her belt, Gracy accepted more offbeat roles.

More substantial roles followed as she got few successful films to her credit in regional languages such as “Santosham” (Telugu), “Loudspeaker”(Malyalam) and “Rama Rama Krishna Krishna”(Telugu). She also starred in Punjabi films such as “Choodiyan”.

I am glad that a role like this came my way.”
