Sir Ian McKellen doesn't believe the final 'Hobbit' film is ''the end of the journey''.

The 75-year-old actor has suggested that there could be another movie based on the fictional Middle-earth, which was created by J.R.R. Tolkien.

Sir Ian - who has played Gandalf in both the 'Lord of the Rings' trilogy and the three 'Hobbit' films - noted that the movies' director Peter Jackson originally thought the process would be finished over a decade ago.

Speaking at the premiere of 'The Hobbit: The Battle of the Five Armies' in London last night (01.12.14), he shared: ''I was told by Peter, in 2001, that that was the end, that it was all over.

''Here we are 13 years later. So I don't believe necessarily this is the end of the journey.''

When asked why he thinks the franchise has been so popular with fans across the globe, the veteran actor explained how the films

strike a moral chore with people.

He told the BBC: ''Maybe [the movies] endure because they're not about evil just for evil's sake, they're not about frightening and exciting things just to thrill the audience.

''They're actually about something important. They're about what it takes to be a good person, really.''
