(Decanter) - Sideways author Rex Pickett says director Alexander Payne fears making a sequel to the hit 2004 film will be 'selling out'. Payne, whose film of Pickett’s book was a worldwide hit which propelled both him and his anti-hero Paul Giamatti to stardom, is no longer answering his emails, Pickett told Decanter.com. 'I think he sees himself as a guy leaving a cinematic legacy. He thinks the sequel is selling out,' said Pickett, who has written a sequel to Sideways, Vertical, which he’s keen to see on the big screen.
