Ridley Scott confirmed as Alien prequel director

They say you can never go back, but apparently Ridley Scott hasn't heard that one because he's been confirmed as the director of the fifth Alien movie, says Variety .

The movie's set to be a prequel to the 1979 classic that Scott directed. Jon Spaihts is on board to write the screenplay.

Scott is currently working on a number of projects including Robin Hood and The A-Team, as well as adaptation of The Forever War.

Is an Alien prequel a better idea now that Scott's on board? What would you hope to see in it? Comments welcome as normal...
