Vin Diesel believes his 'Guardians of the Galaxy' character is similar to his persona in real-life.
The 47-year-old actor insists the innocence of his alter-ego Groot - a genetically modified tree who tries to save the world - in the new Marvel flick is comparable to his own off-screen persona.
He explained: "To maintain your innocence is a feat. So much magic comes from it.
"Ironically, people probably see more of Groot when I'm posting [on Facebook] than they would in any of the characters I play."
However, despite Diesel's love of Facebook, he argues that stars ought to be more aware of the direct interaction social media allows with fans.
He explained: "Imagine if you were able to Facebook Elvis, and talk to him, and hear from him without the Hollywood of it all. That was the 'Fast & Furious' experience."
Meanwhile, 'Guardians of the Galaxy' - which also features the likes of Zoe Saldana, Bradley Cooper and Chris Pratt - is in UK cinemas now.
