Cameron glad 'Terminator' sequels did not surpass originals

James Cameron was glad when the 'Terminator' sequels didn't do as well as his installments of the film.

The director, who was behind both 1984's 'The Terminator' and 1991's 'Terminator 2: Judgement Day', admits he was pleased when 'Terminator 3: Rise of the Machines' and 'Terminator Salvation' did satisfactorily, but didn't want them to outdo his own achievements.
