It'll never happen! While I'm not huge fan of the campy 60's Batman series, King Tut and Egghead were probably the two best villains invented specifically for the show. They are memorable characters primarily because Vincent Price and Victor Boeno were great theatrical performers. King Tut actually almost made an appearance in the "Gotham Adventures" comic! Ty Templeton had a story planned for the character but never wound up going ahead with it. At any rate, here's what an animated King Tut might look like!
POSSIBLE VOICE ACTOR CHOICE: John Goodman
He'd be a good live action King Tut too!
KING TUT'S ORIGIN:
King Tut first appeared in the 60's 'Batman' TV show. I believe he was a history professor who got bonked on the head and began thinking he was King Tut.
