Diesel hints at one of the biggest questions that fans will probably have going into Infinity War too: whether or not it will feature a fully grown Groot or the Baby Groot version fans are getting in this year’s Guardians of the Galaxy Vol. 2.
Still, even Diesel seems uncertain as to which version of Groot will appear in the next Avengers film.
A Groot and Hulk team-up has been one of the most talked about (and wanted) crossovers for the past few years.
All of it will likely come down to the time between the two films, of course, and the Avengers would probably benefit more from having a fully-grown version of Groot on their team.
