EXCLUSIVE
There's no escape, Jack Black ... that Stormtrooper mask is powerless against us!
Despite his best efforts, we were able to catch up with Jack at Comic-Con last night as he walked the streets of San Diego -- hoping to be doing so incognito.
FAIL!
Our cameraman pegged him immediately ... and Jack didn't seem particularly pleased to be outed so easily, but figured he knew why.
"Is it my gut?" Jack asked.
Nope, apparently that wasn't what tipped us off ... check out the video to find out what did.
And may the force be with you, Jack.
