Keira Knightley may be out, but Richard Attenborough – Knightley’s still the better looking of the twosome – is in it seems. Talking to Aint it Cool, a scooper revealed that Attenborough was on BBC5 and says he’ll be back as John Hammond for “Jurassic Park 4”. Aint it Cool adds, “Writer William Monahan has been writing the script from an original story by Stephen Spielberg. We know that it will not take place in the jungle or any "green" environment. We know that Sam Neill and Jeff Goldblum are on board. We know that Stan Winston’s crew are in heavy design mode for the film. We know that there should be a ton of new breeds of dinos, and that Steven has apparently been mining Crichton’s original novel for more unused material ( the river sequence? ) Lastly… we know it is set for Summer 2005”.
