I can't be the only one looking forward to The Rock playing Black Adam in Shazam, due to be released in 2019.
I want a Mentor cameo.
That dude was Les Tremayne - and he died in 2003. So, I'm afraid that request will be denied.
Maybe Michael Gray?
Death is no barrier to Hollywood. His face could be CGIed onto anyone.
Megan's law precludes Mentor and "Uncle" Dudley from being that close to the set.
He could make an off-camera appearance. Say police discovering a wrecked Shazam-van and mentioning it was registered to man named 'Mentor'.
My personal headcanon is that Mentor from the old series was actually supposed to be Mentor (https://en.wikipedia.org/wiki/Mentor_(Odyssey)) (since he said Mentor was his actual name, and he claimed to be old enough to teach archery to Cupid).
Anyway, as much as I love Captain Marvel, I'm not looking forward to anything involving "Shazam" (a character who bears only a superficial resemblance to Captain Marvel), including this movie.
