Phileas Fogg is an eccentric English gentleman living in Victorian London. He's quite a character: a phenomenally wealthy man whose source of income is something of a mystery to his numerous friends and acquaintances. What makes Fogg a particularly interesting character is his insatiable thirst for exploration. With ample wealth and leisure time he can afford to indulge in all manner of crazy adventures, of which circumnavigating the globe in just eighty days is simply the most recent example.
Despite the air of mystery that hangs over him, Fogg is widely regarded as an open, honest individual with a very strict moral code, which he follows to the letter, come what may. We see this, for example, when he risks the ire of the local population by saving Aouda from being thrown onto her late husband's funeral pyre in accordance with established Hindu custom. Fogg is fearless and brave, just the kind of characteristics you need if you're going to traverse the globe with all its unfamiliar cultures.
