Dhaka, May 13 -- Just when fans thought the vault was officially closed, Netflix has sparked fresh speculation around the future of Money Heist.

On Wednesday, Netflix España dropped a surprise teaser with the caption: "The dream continues. The universe of Money Heist expands."

The clip features Alvaro Morte returning as the Professor, surrounded by people in the franchise's iconic red jumpsuits and Salvador Dali masks, while a new version of Bella Ciao plays in the background.

Then comes the line that sets everything off: "The revolution never ends."

From there, things went into overdrive.
