When I think of Harrison Ford (which isn't a lot, but still....), I think of his Indiana Jones persona, semi-tough guy, adventurous - cool.  Well, he's ditched that look and gone with something a bit softer and um, greener.  Harrison, girlfriend Calista Flockhart, Calista's son Liam, 7, and a friend were spotted out trick or treating.  Love the peas in a pod costume!

More pics after the jump!

Liam was a Dodger Dog, his friend was a pretty Princess and Calista was cute as a button as a hippie girl.
