Look at the Time Force cast ... mainly the big three ... Jason Faunt looks his age (30s), Erin Cahill is still gorgeous but will never be able to pull off the "early 20's heart-throb" she did in Time Force, and the Quantum Ranger is balding (it's true! I saw it on a video from Power Morphicon).

The actors I'm pretty sure will never return...

Austin St. John - from all accounts, he'd do it for $$ and nothing more
David Yost - didn't end on a good note, with Saban in control again, they'd all have to bury the hatchet
Amy Jo Johnson - moved on and wants to forget it, even made fun of it at one point (I believe it was a MTV interview way back in the early 2000's).
Most of the Alien Rangers - Maybe the two that showed up to this year's Power Morphicon, but the rest...?
Christopher Kaymen Lee - he's an amateur film director, plus I think he gained a lot of weight, grew a beard, etc.
The guy that played Zhane - Justin Nimo? Who even knows where he is?
The guy that played Titanium Ranger, Ryan something - who knows where he is?
Leo, Maya, Kai, Mike from Lost Galaxy - again, all put in the past
The RPM cast - excluding Eka and Mike Ginn (Eka did the voiceover in Samurai under a stage name, I'll bet anyone $$ on this and Mike showed up to Power Morphicon) ... Mike said his fellow castmates are "reluctant" to come to Power Morphicon, like they don't want to be a part of it, probably from the fall out of Eddie and Judd Lynn

That's a lot of history that doesn't want to be included in the history. I wish they'd change their minds but eh what can you do?
