A Hollywood auction featuring Michael Keaton's Batman costume and dinosaurs from the Jurassic Park franchise has proved a huge success - raising a staggering $4.1 million. The 31st Profiles In History auction's top seller was a rare King Kong six-foot film poster, one of only three known to exist, which sold for $345,000 - over $100,000 more than the reserve price.

Other hits at the event included the Batman costume worn by Keaton in Batman Returns, which was snapped up by a superhero fan for $103,500, with Charles Middleton's Ming The Merciless cape from 1936 movie classic Flash Gordon selling for $115,000.

And movie monsters were another hit of the day, with one collector paying $126,500 for a leaping Alien Warrior figure from Aliens, and a Velociraptor from The Lost World: Jurassic Park II was sold under the hammer for $115,000.

The auction took place on March 27 and 28 in Los Angeles.
