We're not sure how they missed this one.

A bus in Cambridge is advertising a movie that doesn't exist thanks to someone's gaffe. The advertisement, which is meant to be for Ridley Scott's newest blockbuster Alien: Covenant is in stead advertising a movie called "Liaen Oven Can't"

Yeah so it looks like the guy who handles the bus advertisements on Cambridge's buses somehow put the panels on in the above order and didn't think anything of it. We guess he isn't a fan of the series?

To be honest we're kind of intrigued by this new title. Hopefully some enterprising young writer will make something of it.
