Paul Rudd has revealed "not a lot of people care" about his forthcoming movie 'This is Forty'.
The 'Role Models' star explained the director of the film - which will see the actor and Leslie Mann reprise their roles from 2007 motion picture 'Knocked Up' - Judd Apatow is reluctant to reveal too many details about the project because people aren't bothered about it and he doesn't want them to get "sick of it".
Paul said: "Judd was telling someone the other day that it's coming out in a while and he said, 'I don't want people to know about it and get sick of it. But the truth is so few people really care. It's not like we're Terrence Malik here.'"
The 42-year-old actor insisted the spin-off movie - which will also see Charlyne Yi reprise her role as Jodi - is not a sequel, but simply tells the story of Pete (Paul) and his wife Debbie (Leslie), who is the sister of Alison Scott (Katherine Heigl) from 'Knocked Up'.
Paul added to Collider: "It's really like our story but it's not like a sequel, it's just checking in with us."
