Jack Black is all over San Diego Comic-Con — but if you don't know where to look, you might miss him.

But we know where to look. Speaking with MTV News at Comic-Con, Black told us that he's been walking the floor wearing a "Star Wars" stormtrooper helmet — not for fun, mind you, but for business.

"A lot of people wanted photos, so I didn't have a chance to buy things. So I bought this thing," said the "Goosebumps" actor, putting on his Stormtrooper helmet. Unfortunately for Black, word of his new disguise spread around the convention floor very quickly.

"I put it on, and I'm walking around trying to buy some more things at the Comic-Con, and somehow, the word got out," he said. "And everybody's just like, 'Jack Black, you in there?' And I'm like 'No, it's not me. I don't know what you're talking about.'"

Poor Jack. All he wants to do is run around the Comic-Con floor and purchase new additions to his "Lord of the Rings" collection.

"I like to collect my 'Lord of the Rings' figurines," he said. "They're not figurines; they're more like statues. Statuettes."

Beyond "Lord of the Rings," there's one other pop culture icon that Black nerds out over: The Incredible Hulk.

"I was really into Hulk [as a kid]," he said. "I don't know what it was. He's the strongest possible creature in the universe, and I thought that was pretty badass."

Equally badass: the Red Hulk statue Black purchased during his Comic-Con adventures. "I don't know what he is," he confessed. "I never read the comic book where he turned red. I think that's from another dimension."

Actually, Red Hulk is totally from the same dimension as the original Hulk, and is a different character entirely, but that's OK; Black's geek cred already speaks for itself.
