10 Announced Movies That Mysteriously Disappeared

As of late, Sony seems to be getting on the right track with its video-game-to-movie adaptations, setting up an in-house division called PlayStation Productions to handle upcoming film projects like Uncharted, and Ghost Of Tsushima.

In the mid-2010s though, the company had a few stumbles. One of those was the doomed big-screen adaptation of Sly Cooper, which was announced in 2014 alongside a slick teaser trailer, only to vanish into development hell.

In 2016, director Kevin Munroe indicated that the movie hadn't even entered production yet, later revealing that the project had been on standstill for over a year.

Animation studio Rainmaker then stated that the poor box-office performance of the Ratchet & Clank movie had caused them to re-evaluate Sly Cooper, and they ended up leaving the project in 2017.

The failure of Ratchet & Clank clearly put Sly Cooper on hold, but technically, it's never been cancelled. It's speculated that the remnants of the movie were recycled for the Sly Cooper TV series - which, funnily enough, is also in development hell - but it's unclear exactly what happened here.

In 2022, he took charge of WhoCulture and has grown it into the biggest Doctor Who channel on YouTube, and one of the biggest Doctor Who communities on the web full-stop. He has been writing and video editing since his early teens, and first got a taste for content creation after making his own Doctor Who trailers, off the back of a burning obsession with the Matt Smith era of the show. Like many his age, he first got into Doctor Who with the 2005 revival, but has since gone back and fallen in love with the classic years too. If you need someone to recite every Doctor Who episode in order, or to give you a random factoid about the making of Gridlock, Danny is the person to ask!
