"I don't like simple girls anymore,'' The Hindustan Times over the weekend quoted Varma as saying.
Varma, who has made some 30 Hindi-language movies, is one of the rare Indian directors whose films don't feature song-and-dance routines that often fill Bollywood films.
"My perception about a woman has changed over the years _ she has to be sensual and have the oomph factor,'' he said.
His recent movie about an underworld kingpin, "Sarkar,'' or "Boss,'' was a huge box office success.
His forthcoming film "Nishabd,'' or "Wordless,'' features Bollywood icon Amitabh Bachchan, 63, and debutante 19-year-old Jiah Khan.
In the film, being readied for a release later this year, Bachchan plays an aging romantic who falls in love with a young woman.
"Nishabd revolves around the fact that while the body aches, feelings don't. The film is strong on physicality, but that is needed to bring out the contrast between desires and reality,'' he was quoted as saying.
Varma recently said "Nishabd'' is inspired by Vladimir Nabokov's famous novel "Lolita'' but that his characters are driven by love, not sexual obsession.
