There appears to be a deleted scene, generating a continuity goof. Batman and Robin are caught in the net, and Batman says that he'll cut them free. The camera immediately cuts away. When Archer and his gang come down a minute later, Batman and Robin are unconscious for no apparent reason.
Batman says that Dick Clark is from Philadelphia because of the way he speaks. In reality, Dick Clark was born in Mount Vernon, New York but moved to Philadelphia where he was a disc jockey and eventually started American Bandstand.

A villain named "The Archer" first appeared in Superman #13 (November-December 1941). The criminal wore a green archer's costume and worked alone, extorting money from wealthy victims whom he would murder if they refused to pay.
Beginning this season, all of the action word titles which appear during the climactic fight sequences were inserted in-between scenes, as opposed to being superimposed over scenes like the first season and the movie, due to cutting down the massive budget devoted to camera and art work.
Archer: Parting is such sweet sorrow.
Referencing the famous line from William Shakespeare's play Romeo and Juliet, Act 2, Scene 2. The full line is "Good Night, Good night! Parting is such sweet sorrow, that I shall say good night till it be morrow."
Alfred: I was known as the William Tell of Liverpool.
Referencing the 15th century Swiss folk hero first mentioned in White Book of Samen (1475). A legendary marksman, Tell is forced to shoot an apple from his son's head so that a tyrannical ruler, Gessler, will spare Tell and his son. Tell escapes, later kills Gessler, and leads a rebellion against the Hapsburg emperors, creating the Swiss Confederation.
