Jeff Garlin has revealed he thinks he and Steve Coogan canned a sitcom they were writing together because Coogan "lost interest".
The Curb Your Enthusiasm actor is a huge Alan Partridge fan and lobbied to get Coogan in a guest role on the show, back in series six.
For a while they started writing a sitcom for HBO together, but the project didn't work out.
Jeff said: "I like writing in the morning, he likes it in the afternoon. We were both pretty good at lunch, but I ran out of steam at 12 o'clock and he'd not even started up yet, so I think he lost interest."
The comedian, who voiced the Captain in Wall-E and Buttercup the unicorn in Toy Story, is set to lend his voice to forthcoming animation Paranorman - by the people who made Coraline - and, if he's lucky, there'll be another series of Curb on the horizon, but only when it suits Larry David.
"We never know when Larry is going to do another series. I thought series five was going to be the last year. But this is the secret to why Curb is great. Larry David is really rich, therefore his motivation is purely creative in terms of doing more seasons.
"And let's hope he's still feeling creative - as I would do Curb forever if I could," he said.
:: Curb Your Enthusiasm continues on More4 on Sundays. Ricky Gervais appears on the show tonight (October 23).
