Just on the subject of Jor-el & Ka-el; the creators of Superman were both Jewish and it may be interest to note that biblical names that end in "el" such as Ezekiel, Michael, Gabriel etc all mean "something of God". (with the "el" being God)

Didn’t know that SDM. Interesting to know.

Cheers, buddy.

And to the OP. Big Daddy is correct, you will find many examples of such motifs in literature, film, art, etc. It always adds to the understanding and further enriches the work. Usually, it is not necessary to catch the allusions, but when one does it only enhances the enjoyment of the work. (And I don’t say this as related to Religion, but in the context of appreciation for the work.)
