Predicting 20 Comic Book Movies Announced In 2017
20. Rocket & Groot
Rocket and Groot have got spin-off potential written all over them. Not only is Groot one of the most marketable properties in the entire cinematic world at the minute (he's adorable, what more do you want?!), but their relationship poses lots of questions that the films are yet to really address.
The best approach to such a spin-off would probably be to focus on how the pair came together, with a prequel perhaps filling in some of the gaps in what we know of Rocket's tragic backstory, as well as expanding on why they're so close.
Rocket is basically the Han Solo of the Guardians crew (no matter what Star-Lord claims), and if he can have his own spin-off establishing where his legend came from, then so should Rocket.
Evidence?
James Gunn has already spoken several times about his attraction to making a Guardians spin-off - probably in place of a threequel in fact - and Vin Diesel has already hinted (in his usual over-sharing manner) that the film could be on the cards.
