Batman Forever1995

[Alfred brings an envelope to Bruce, who's watching news reports on the Riddler]

Alfred:
Apparently you and Batman have a common enemy. That was with the morning mail.

[Bruce opens the envelope, revealing another riddle, the camera cuts to the two of them in the Batcave]

Alfred:
"The eight of us go forth, not back; to protect our king from a foe's attack."

Bruce Wayne:
Chess pawns. Clock...match...all physical objects, man-made.

Alfred:
Small in size, light in weight.

Bruce Wayne:
What's the connection?

Alfred:
With all due respect, sir, I believe that's why they call him "the Riddler".
