The Telegraph is reporting that Daniel and Emma will be in the Guinness Book of World Records.

Daniel Radcliffe and Emma Watson have entered the Guinness World Records book as the highest grossing lead actors of the decade.

Despite their tender years – Watson is 19, while Radcliffe celebrated his 20th birthday in July – the duo have outstripped the fortunes of their Hollywood rivals thanks to the success of the Harry Potter films.

The figures from the new edition of Guinness World Records is based on box office takings. The first six Harry Potter films have grossed $5.4 billion, and there are two more to come.

Radcliffe’s films earn an average of $558 million, while Watson is ahead of $753.7 million as last year she also starred in The Tale of Despereaux, a children’s animation in which she voiced a princess.

All I have to say is WHERE IS RUPERT! Why do they always forget about him…shouldn’t he be included with them? Maybe its because he isn’t a lead…UGH!

UPDATE: Sky News has some more information about this:

Lead star Radcliffe was named “highest grossing actor of the decade” as his films earned an average of just under £400m at the box office, while Watson, who plays Hermione, took the record for “highest average box-office gross for an actress”.

Guinness World Records 2010 goes on sale on Thursday.
