Entertainment Weekly interviewed Executive Producer David X. Cohen about his and creator Matt Groening’s plans for the re-animated series.
“Matt and I decided to make sure people knew right away that this was Futurama in its classic half-hour form. We wanted to quickly establish in the first episode that the characters are back from their DVD adventures. Fry and Leela return relatively quickly. Very quickly we get back to the Planet Express headquarters in New New York City — and the only slight hitch is that everybody is dead. “
(Everyone but Fry and Professor Farnsworth, it appears.)
“That episode is entitled ‘Rebirth’. We’ll get to see the Professor’s birthing machine and all the glory of artificial rebirth. It’s both a literal and figurative rebirth of the series.”
