Ian McKellen says he cannot write his autobiography without knowing how he will die.

The veteran actor told Empire magazine that he planned instead to regularly update his official website.

He revealed: "I'll never put my memoirs in print. What's upsetting about an autobiography is that the final chapter is always missing. I mean, you want the death, don't you? There's more on that site than there could ever be in a book. Eventually, before I die, I hope to have written about every part I've played."
