Though set in England, Flashman is another fun Italian production from the late 60s that leans on attempted humor and is heavily inspired by Batman. He's even got a very Battish theme song. The somewhat convoluted plot concerns two gang of thieves who rob the same bank. One is a band of babes headed by a ruthless woman the other is a group of thugs lead by a guy who has a serum that can turn anyone invisible. The employee they rob is none other than Flashman in disguise.
