Apoorupam 

Dear friends, Apoorupam is not her debit film. If it was then Chopra must have said about it.
She says her only first film released was Thamizhan. Apuroopam was actual a 2003 film, but you will find 2002 or even 2001 in many fancruft sites. Here is link which says, it was delayed and was a 2003 film, means after Thamizhan, so it's not her debut.
