As a writer on the show in the early '90s, O'Brien was responsible for fan favorite episode 'Marge vs. the Monorail' in its 4th season, among others. However, he ended his contract early to replace David Letterman on NBC's Late Night talk show in 1993.
Speaking exclusively to Entertainment Weekly, O'Brien said:
"I cleared my talk show schedule for a year at great financial cost to myself, got an apartment right outside the Fox lot, and told them I was ready to report to work. All I heard back was that they were having trouble finding me a parking space, and then they stopped returning my calls altogether. I am stunned and disappointed.... Truth be told, I worry that the Simpsons-writing portion of my brain has been destroyed after 14 years of talking to Lindsay Lohan and that guy from One Tree Hill, so maybe it's all for the best.''
With or without Conan on board, reports of the film's hilarity have been trickling out online for months. The general consensus is that, at the very least, this is going to be the best Simpsons "episode" in over a decade - if not ever - and the look of the film is surprisingly cinematic, without losing the series' simple charm.
After months of disappointing blockbusters, could it be possible The Simpsons Movie may just be the saving grace of the season? I lost track of the show years ago but, honestly, I couldn't be more excited.
As for Conan, perhaps they might return his calls for a sequel?
