James Francos acting skills are unique: Freida Pinto

London: Actress Frieda Pinto is impressed by her `Rise of the Planet of the Apes` co-star James Franco`s "unconventional" acting style, which helped her learn a lot.

Pinto, who shot to fame playing Latika in the 2008 Academy-award-winning film `Slumdog Millionaire`, stars alongside Franco, 33, in the sci-fi, reported Total Film magazine.

"He`s got his own unique and distinctive style of acting. It`s not conventional at all. It does take you by surprise initially, but it`s all about being flexible and trying to understand how another actor works. I found a lot of things in his acting style that I could pick up and learn from," said Pinto.

Pinto, 26, explained that she opted for the film because it humanised chimpanzees.

"I play a primatologist and I have dedicated my entire life to chimpanzees. Caroline is the voice of reason but it`s a nice voice of reason without being preachy.
