Activist investor Nelson Peltz said he plans to nominate himself and former Disney Chief Financial Officer Jay Rasulo to Disney’s board, weeks after the company rebuffed Peltz’s previous request to become a director.

The announcement is the latest twist in a proxy battle between Peltz’s Trian Fund Management and Disney—the fund’s second campaign against the entertainment giant in a year—which has pitted the 81-year-old investor against 72-year-old Bob Iger, who returned to Disney a year ago for a second stint as CEO.
