Vin Diesel has apparently seen a finished version of Guardians Of The Galaxy, and has been raving about the film’s fun-for-all-the-family appeal.

The star, who voices the sentient tree known as Groot, took his young family to see a special screening of the film, and was blown away by how inclusive it is…

“My youngest who is 3 yrs old, has never been to a movie theatre before in his life,” said Diesel via Facebook. “Today, I was invited by Disney and Marvel to see the latest cut of Guardians Of The Galaxy and I was able to take the angels. WOW!!!!!”

“To Marvel, Disney, the incredible cast and team and especially James Gunn… Thank you for making a GREAT MOVIE! It was amazing and will always be special, for it was the first film I was able to take my family to see and oh how they loved it.”

That’s some nice salesmanship from Diesel there, who pleasingly signed off the post with his new catchphrase, “I AM GROOT!!!” Yes you are, sir. Yes you are.

Directed by James Gunn and co-starring Chris Pratt, Zoe Saldana and Bradley Cooper, Guardians Of The Galaxy will open in the UK on 1 August 2014.
