Robert De Niro has revealed re-watching his film Goodfellas helped him to prepare for his role in The Family.
The Oscar-winning actor, who played gangster Jimmy Conway in Martin Scorsese's 1990 film, decided to see his previous work again before filming on Luc Besson's mob movie started.
"I looked at the movie and the DVD, and actually there were things on the DVD I hadn't been aware of. So I went through the whole film carefully and then I went through the other stuff on the DVD. It was good and helpful for me," he said.
In The Family, Robert plays ex-Mafia boss Giovanni Manzoni, who is hiding in France with his family, including his wife Maggie (Michelle Pfeiffer), daughter Belle (Dianna Agron) and son Warren (John D'Leo) after he betrayed his mob mates.
The 70-year-old, who has portrayed gangsters in The Godfather, The Untouchables and Casino, was attracted to the part because of the humour and its original take on the mob movie.
"(I'll do it) if it's written well, it's fun to do and the characters are interesting, especially if I'm doing them with Luc and Martin Scorsese," he said.
"This is an unusual take on the mobster genre with a novel storyline. My character was a crime boss in New York, but he turned in his whole crew," he added.
Robert also said he has no interest in writing a biography.
"I have been [approached] but I haven't really entertained it much. It takes time to do that and I just haven't. Once Scorsese and I were thinking of doing a book together and we might still. I don't know but that was as far as it went," he revealed.
:: The Family opens in cinemas on November 22.
