James Gunn has revealed 'Guardians of the Galaxy 2' will ''focus more intensely on some of the characters''.

The 44-year-old director - who helmed the first movie in 2014 and has returned for the next instalment - has promised the eagerly-awaited new movie will be even better than the original.

He said: ''It's both a bigger movie and a smaller movie because we focus more intensely on some of the characters.

''We get to learn a lot more about fathers in the second movie, and we focus a lot on that.''

James also suggested the upcoming movie will see new characters enter the Marvel universe.

Asked if fans should expect to see any new characters, he told Collider: ''You'll have to wait to see the movie to see who's introduced.''

Meanwhile, Chris Pratt claimed recently that starring in 'Jurassic World' was a ''breeze'' after appearing in 'Guardians of the Galaxy'.

Chris - who appears in the role of Velociraptor expert Owen Grady - said: ''To be honest, after Groot and Rocket on 'Guardians Of The Galaxy', a few dinosaurs are a breeze.''

'Guardians of the Galaxy 2' is set for release in May 2017.
