During the '80s, Hasbro treated the G.I. Joe and Transformers toy lines like two separate completely franchises although their respective animated series hinted that they shared the same universe. Now, the crossover is finally going to take place on the big screen.

Via SlashFilm, Paramount formally announced the Transformers and G.I. Joe crossover movie at CinemaCon. The news isn't too surprising given that G.I. Joe was referenced in Transformers: Rise of the Beasts. But it's unclear if the new film will build on the continuity of Rise of the Beasts or if it will be a fresh start for both franchises. Steven Spielberg will produce the crossover movie, which doesn't currently have a release date or a director.

Earlier this year, producer Lorenzo di Bonaventura hinted that a Transformers/G.I. Joe crossover movie could arrive as soon as 2026. He also shed some light on the approach to the film.
