There is an uncomfirmed report that Christopher Reeve has died.

According to the Drudge Report, the Los Angeles based journalist Nikki
Finke is reporting that actor Christopher Reeve is dead. He died
suddenly Sunday. News of his death has not been reported publicly yet.
His family will make an announcement Monday at the earliest.

Reeve was mentioned Friday in the second presidential debate by John
Kerry. Stating that he was a friend of the paralysed Reeve, Kerry said
he was in favor of further stem cell research because Reeve could
possibly walk again one day thanks to such science.
