Director Spike Jonze thinks Scarlett Johansson is a good actress as she is happy to show her emotions.
The "Her" director praised Johansson for bringing life and character to the role of the computer, which falls in love with a human, reports contactmusic.com.
"Scarlett is not afraid of revealing her pain and emotions. She's attractive, but also smart as hell. She's in some renaissance age, where she is pushing herself to new places. She wants to go deeper and is taking risks," said Jonze.
