Played by Dan Fogler
Jacob Kowalski is an American Muggle who is madly in love with Queenie Goldstein. When she broke his heart by choosing to follow Grindelwald, his whole world fell apart; he no longer takes joy even in his beloved bakery in New York City. When he is first approached about venturing back into the wizarding world, his immediate reaction is to want no part of it. But despite his objections, Jacob can’t turn down any chance to find and be reunited with Queenie. Teaming up again with his best friend, Newt Scamander, this Muggle—who always wanted to be a wizard—is presented with a special gift from Dumbledore that makes him feel truly a part of the group.
