Two-time Oscar winner Jodie Foster plays a vengeance killer in her latest film, but in real life she gets angry at electronic gadgets, not at people.

"I have a problem with electronics. I can't ever make them work. It drives me crazy," she told a news conference in Tokyo to promote The Brave One.

In the thriller, Foster plays a Manhattan radio personality who goes on a killing spree after her fiancee is murdered in a Central Park attack.

A reporter asked if there was anyone in real life she wanted to take revenge on.

"It's the only time where I lose my temper, is on inanimate metal objects," she said, to chuckles from the audience.
