Daniel Radcliffe is confirmed to make another screen appearance apart from the Harry Potter films and the December Boys movie (currently filming), and this time it'll be on the HBO and BBC Two television comedy next to Ricky Gervais called Extras. Here's a snippet of the article from the UK Comedy Guide, Chortle:
Harry Potter star Daniel Radcliffe is to appear in the second series [season] of Extras. He is the first actor to be confirmed for one of the cameo roles.
A BBC insider was today quoted as saying: ‘The idea is to blow apart the theory he's a clean-living schoolboy who is a bit posh and portray him as a thuggish yob.’
Update: BBC's Comedy Blog has also mentioned this piece of news, however states "it's not yet decided in what capacity [Dan will] appear".
