Am I the only one who made the connection?

AP reported that Nicholas Cage & his wife had a baby boy that they named Kal-el Coppola Cage. I'm not exactly huge into comic books/graphic novels or anything, but isn't Kal-el Clark Kent/Superman's Kryptonian name?

Is Nicholas Cage trying to send out a msg that he wants to play a young Jor-El in a future Superman movie?
