Judd Apatow has insisted an R-rated comedy could still be a huge box office hit.
The 57-year-old actor - who has appeared in movies like 'The 40-Year-Old Virgin' and 'Knocked Up' as well as producing the likes of 'Superbad' and 'Step Brothers' and more over the years - has insisted "one person with a great idea" is all that's needed to give the genre a revival by inspiring everyone to "do it again".
