Chris Pratt has been "overwhelmed by feelings of enthusiasm, joy, gratitude, conviviality, camaraderie, elation and exhilaration" since he started working on 'Guardians of the Galaxy 2'.
The 36-year-old actor has just started shooting the Marvel Studios sequel in which he reprises his role as Star-Lord and after getting stuck into the script he is beyond excited about bringing the story to life on the big screen.
In a post on his Instagram account, he shared: "Feels good to be back in action on Guardians of the Galaxy Volume 2!!! I can't even tell you how excited I am. Ok I'll try. I'm ecstatic. I'm bursting with joy. I'm overwhelmed by feelings of enthusiasm, joy, gratitude, conviviality, camaraderie, elation, exhilaration. I just used an online thesaurus for these words. I suggest trying that. That way instead of saying 'I'm very excited' say, 'I'm exhilarated.' Never too late to learn words. The pen is mightier than the sword. I never got that. I could whoop someone's ass if I had a sword and they only had a pen. WAIT!!! Now I get it. Cause you could use a giant pen with a dagger on one end? And a gun on the other end? No? Whatever. (sic)"
And Pratt - who has three-year-old son Jack with wife Anna Faris - has jokingly boasted the sci-fi superhero sequel will be the "greatest spectacle film of all time".
He added: "Guardians of the Galaxy Vol 2. Is going to be the greatest spectacle film of all time. This is not.... bear with me... using online thesaurus..... Hyperbole! This is not hyperbole! (sic)"
As well as the return of Pratt, Zoe Saldana, Dave Bautista, Vin Diesel, Bradley Cooper, Michael Rooker and Karen Gillan are all reprising their roles from the first film - which was released in 2014 and was a big box office success - while James Gunn will direct again.
