Disney chief executive Michael Eisner has admitted relations with Pixar could be salvaged.

Eisner told investors at Sanford Bernstein's Annual Strategic Decisions Conference on Wednesday that "I will not believe it is over until it is over".

"I am just an eternal optimist," he added, according to a Forbes report.

Eisner, who has been criticized for letting the deal with Pixar end, confirmed that discussions, which broke off early this year, had not reopened.

However, Eisner insisted that Pixar – whose CEO Steve Jobs holds the same post at Apple – will benefit from Disney's marketing machine.

Jobs has said he is in no hurry to strike a new distribution alliance.
