A film prop auction raised almost £4 million - including £30,500 for Marty McFly's self-lacing trainers.
The UK's largest ever memorabilia auction also included Chris Pratt's Guardians of the Galaxy helmet, which went for £134,200, and a bullwhip used by Harrison Ford in Indiana Jones for £79,300.
Prop Store, who held the auction in partnership with Odeon, flogged more than 600 items from blockbusters including Pulp Fiction and Top Gun at the BFI Imax on Tuesday.
Other pricey props included Merlin's robe and helmet from the 1981 film Excalibur, which went for £91,500, and Jack Nicholson's Joker costume, which sold for £39,650.
The sale coincided with a number of special screenings at the BFI IMAX, which saw classics such Aliens, Scarface and Who Framed Roger Rabbit? return to the brig screen for film fans to enjoy in the lead up.
