Ridley Scott won't be directing the 'Blade Runner' sequel.

The 76-year-old director - who helmed the original sci-fi thriller in 1982 - has confessed he will not be returning to the director's chair for the follow up but has signed on to produce the film.

While the new director is yet to be revealed, Scott has been working with original writer Hampton Fencher to come up with a plot for the movie.

He told Variety.com: ''We talked at length about what it could be, and came up with a pretty strong three-act storyline, and it all makes sense in terms of how it relates to the first one.''

The Oscar-nominee also revealed that Harrison Ford - who starred as Rick Deckard in the original - will be returning in the sequel, although his character will only be making an appearance towards the end of the film.

He said: ''Harrison is very much part of this one, but really it's about finding him; he comes in the third act.''

The 'Prometheus' director - whose latest offering 'Exodus: Gods and Kings' starring Christian Bale and Ben Kingsley is due out in December this year - also confessed he has no plans to retire in the future.

He said: ''If I stop, what am I going to do? Walk a spaniel?''

He added of his non-stop career directing both movies and TV commercials: ''It was almost like being in sport.

''I thought, 'How many tournaments can I play?'''
