The lightsaber Darth Vader swings in the Cloud City duel, the scene in which he tells Luke Skywalker 'I am your father' and severs his hand, is back on the auction block, with bidding set to open at $1 million (£756,000).
It is the same blade that took the hand off. And it returns to sale only months after that hand, still clutching Luke's own lightsaber, set the record for the most valuable prop in the franchise's history.
