"They've come up with something bigger and better for the next two movies," Bloom told Radio, "They had to top the skeletal pirate thing and I think they've really managed it, haven't they?"
He continued: "There's this sequence with a Kracken - it's a big squid - and some other things...oh, was that too much information?!"
Co-star Keira Knightley added: "I have a sword fight with two swords, which has been the biggest challenge, but also the thing that I'm most excited about because it's fantastic. I was well impressed!"
Two sequels are currently being filmed back-to-back, with the first - Dead Man's Chest - set for a July 7, 2006 release.
