Although the movie won't be released for another four months, fans have already spotted a major mistake in
this promotional picture from
Harry Potter and the Goblet of Fire. Not only is Lord Voldemort's name etched on the gravestone, but the dates of birth and death are incorrect as well (Voldemort was born on December 31, 1926).
The Daily Telegraph reports that film producers "are said to be considering altering the tombstone with the latest computer wizardry. They have ruled out re-shooting scenes involving Radcliffe. But it is unlikely they can simply ignore the issue after it led to a fierce online debate."
