She starred in Karz (1980) and in Maharajas (1987), a BBC docu-drama adapted from the book by Charles Allen. In early eighties, she turned her attention to writing and directing, thereby forming her own company, Siga Arts International. She produced a TV series called A Woman’s World (1983) and made a documentary called Living Legend Raj Kapoor (1984) that was aired in Channel Four UK.
She produced a Hindi feature film and made TV commercials, which won her the first prize in the 1988 Paters Award in Australia. In 1999 she won the Screen Awards for Best Talk Show and Best Anchor. Today, she is the anchor of the talk show Rendezvous With Simi Garewal. She is popularly known as “Lady in White” due to her signature white clothes.
