Even in death, "Superman" star Christopher Reeve is promoting human embryonic stem cell research.
The paralyzed actor stars in a new TV commercial in support of a California ballot measure that would devote $3 billion to stem cell experiments. The 30-second spot was filmed about a week before Reeve died Oct. 10.
"Stem cells have already cured paralysis in animals," Reeve says, referring to work with paralyzed rats that were able to walk again after being injected with stem cells at the University of California at Irvine.
The spot was to begin airing Friday, the day after Reeve's widow endorsed Democratic Sen. John F. Kerry for president.
Opponents of the ballot measure decried the ad as "playing on the fears of those who are sick."
