'Star Wars: Episode VII - The Force Awakens' is going to be the ''best Star Wars you've ever seen''.

Drew Struzan, who is working on the poster art for the franchise's seventh instalment, has revealed he has been incredibly impressed by the half of the movie he has seen already.

He said: ''I've never worked with J.J. [Abrams, the director] before and so we started working on it and he showed me like half the movie and it was just ... a wonderful film and I know it's going to be grand.

''I got to read the script and subsequently I've seen half of it and I can tell you and the fans this, honest to god, it is far and away probably going to be the best Star Wars you've ever seen.''

And Drew - who unveiled the first poster recently at the Disney D23 Expo - also revealed details about the process he undergoes when creating the artwork for a blockbuster like 'Star Wars'.

He added to Movie Weekly: ''Having seen the film I know what it is about.

''I got familiar with the characters, so I know what they're portraying in their feelings. So I paint the situation and I paint the feelings. Not to tell the story, but to tell you how you're going to feel when you see the film.''
