Seth Rogen Not In Apatow's "This Is Forty"

Seth Rogen will NOT be amongst the cast of Judd Apatow’s "This Is Forty", the upcoming spin-off of 2007 comedy "Knocked Up" says Movies.com.

Rogen confessed that he will not be reprising the role of Ben from 'Knocked' and added "It was a good choice, honestly, because I think it would've confused people… But I'm really looking forward to seeing it; I thought the script was unbelievably funny."

The story instead will focus entirely on the characters played by Leslie Mann and Paul Rudd in the first film.
