Judd Apatow’s ‘The Simpsons’ episode to air this week 25 years after he wrote it

'Knocked Up' writer-director wrote the episode when he was a virtually unknown stand-up comic

An episode of The Simpsons written by Judd Apatow is to premiere this week – 25 years after the Knocked Up writer-director penned it.

Apatow wrote the episode, which is titled ‘Bart’s New Friend’, back in 1990 when he was a virtually unknown stand-up comic. Apatow, then 22, sent the script to The Simpsons‘ production team, but never heard back from them.

However, after Apatow discussed the lost script in an interview last year (2014), The Simpsons‘ executive producer Al Jean dug it out from the vaults and the episode has now been made. It will air this Sunday (January 11) on US network Fox.

“It’s a pretty rough script — when I reread it I wasn’t exactly glowing with pride — but Al and the staff did their Simpsons magic on it,” Apatow told TV Guide. “They were very collaborative and very respectful but everything they wanted to do was so much better than anything I could think up. They turned my messy little effort into Cinderella.”

Discussing the plot of his episode, Apatow teased: “Homer gets hypnotised and thinks he’s a 10-year-old. He has such a great time being Bart’s friend that he doesn’t want to become an adult again…”
