According to reports, the comic book crossover event is getting its big-screen treatment.

A solo Hulk movie is currently in development, rumoured to be titled 'World War Hulk'.

This will mean that Mark Ruffalo, who joined the MCU as the mean, green, smashing machine in 'The Avengers' (following two failed outings with Eric Bana and Edward Norton), will finally be getting his solo outing over 10 years later.

According to reports, production on the film will begin in late 2022. A likely release window of the film will see it in cinemas in either late 2023 or early 2024. Marvel's ever-shifting release slate currently runs until 'Ant-Man and The Wasp: Quantumania', set for release on July 28, 2023.

With Disney+'s 'She-Hulk' series currently in production and due to arrive at some point in 2022, the TV series will more than likely lead into the MCU's first official solo outing for the Jade Giant.

For those unfamiliar with the comic of the same name, 'World War Hulk' was a limited series crossover release in 2007, created by Greg Pak. The storyline came after the release of 'Planet Hulk', which we had a glimpse of in 'Thor: Ragnarok'. Should the film be heavily inspired by the comic books, 'World War Hulk' sees the gamma-radiated hero return to Earth wanting to deliver revenge against a covert secret society of superheroes, the Illuminati.

This supergroup included superheroes such as Professor X from the X-Men, Captain America, Doctor Strange, Iron Man and Black Panther. So, with Hulk currently back on Earth (last time we saw him in 'Avengers: Endgame', anyway), it appears there's a lot more of Hulk's story to be told until we get to this story arc - or an adapted version of it.

However, the film rights to the character of Hulk currently throw the legitimacy of a solo film of the character in doubt, or it possibly means that the rights have since reverted back to Marvel. Universal Pictures has held the rights to any Hulk movies, meaning if Disney wished to create a solo outing for the character, they'd have to share the profits with Universal. However, this could potentially mean that Universal has now lost the rights to the character.

'She-Hulk' is likely going to play a huge part in the build-up to this rumoured Marvel release. Tatiana Maslany will play the title character of lawyer Jennifer Walters, the cousin of Bruce Banner. Jameela Jamil has been cast as the supervillain Tatiana.
