"Oh Batman my Batman! I'm standing on my chair to honor #adamwest - the man whose portrayal of costumed justice made me wanna be a good person when I was a boy. The #adamwestbatman was my first Batman at age 4. His performance was campy to most, but to me, that's how true heroes spoke... He was pure love and joy. He remained my hero, even in adulthood, as well as a real life role model for interacting with fans," filmmaker Kevin Smith said on Instagram.
