If there's one thing that sets the 1960s Batman apart from its cinematic followers, it's an overwhelming sense of fun. The Gotham of 1966 was splashed with color. Peeking at behind-the-scenes pictures from the set, the production seemed like a blast, as well.

No wonder notable celebrities were lining up to play the villains of the Caped Crusader. They hardly needed the Joker's gas to put smiles on the faces of the cast.

Adam West, Burt Ward, Julie Newmar, Yvonne Craig — even Mr. Freeze — had a blast.

Let's take a look at some snapshots from the Batman set, largely from the TV show, but a few from the movie, as well.
