Four more Transformers movies are gearing up to roll into cinemas, according to Stephen J Davis, chief content office for Hasbro, the American toymakers behind the successful movie franchise.

Davis was speaking at a keynote session at Mipjunior, the annual convention oriented towards children’s TV that takes place in Cannes prior to its parent event, Mipcom (International Market of Communications Programmes).

Davis said: “We just finished ... an incredible experience. We decided that we wanted to plot out the next 10 years of the Transformers franchise, so we got together in a room over a three-month period of time.”

In the room, he said, were nine of the most creative writers he had ever worked with, shepherded by Akiva Goldsman, who won an Academy award for A Beautiful Mind. “They plotted out the next 10 years of Transformers. Similarly, we are doing the same in television and in digital. So stay tuned, Transformers 5 is on its way, and 6 and 7 and 8.”

Davis’s comments added more detail to the announcement earlier this year by Transformers producing studio Paramount that a general “expansion” of the Transformers “universe” was under way, with screenwriter Goldsman heading a team of writers to develop ideas for spin-offs and sequels.

A modestly successful Transformers film was released in 1986, but the franchise was kicked into high gear with the 2007 blockbuster, directed by Michael Bay, which took more than $770m worldwide. Bay then directed three further Transformers films, the most successful globally being 2011’s Transformers: Dark of the Moon ($1.12bn), closely followed by Transformers: Age of Extinction ($1.1bn).
