Gandolfini's temper ‘useless

James Gandolfini

James Gandolfini says, unlike Tony Soprano, he has a "useless temper".

The actor who plays the violent mob boss on The Sopranos, is shooting the sixth and final season of the show.

"I have a little bit of a temper, but it's ... a useless temper," Gandolfini said. "It doesn't accomplish anything, generally. It's just a lot of ranting and raving and nothing, so David [Chase, the writer and creator] probably saw that and put it into the character.

" All writers are vampires and ... they'll look around and they watch you when you're not even thinking they're watching you and they'll slip stuff in."
