The film was shot in Goa where Konkani is the main language so while on sets Deepika got a chance to speak and over hear a lot of Konkani from the local crew.
Deepika is well versed with language but while shooting 'Finding Fanny' she got back into the rhythm of speaking the language much more fluently.
Infact even in the movie, Angie's diction and manner of speaking was deeply Konkani and it made it easy for Deepika to catch up with it.
While Deepika has essayed various different characters like Veronica in Cocktail to Naina in YJHD to a south Indian girl Meenama in Chennai Express to a feisty Gujarati girl in Ram Leela... The character of Angie from Finding Fanny is very close to her.
