I like the insane Avery from American Dad.Frakes did some directing,burton directed some episode for ENT what he has been doing I don't know .Dorn did some various things he was in I am Weasel and Ted 2 and the others haven't got the foggiest Sirtis was in some direct to video movie about football(Soccer) hooligans in prison where she plays an mean and corrupt warden.

Marina Sirtis has also appeared on NCIS a few times as the director of Israel's Mossad. But if you didn't know it was her, you wouldn't recognize her. She doesn't look at all similar.

Well she looked very different in that movie playing a Warden she was quite "big" though I thinks she looks better nowadays

Really?

You think that looks better than Troi? Wow.

No nowadays Sirtis looks a bit less chunkier than in the video.

Two weeks ago (August 3, 2018):

Jonathan Frakes (William Riker) and Marina Sirtis (Deanna Troi) at Star Trek: Las Vegas Convention.

Well she certainly looks better in that last video than in the video I posted.

Here's Wil Wheaton on the CBS TV sitcom "The Big Bang Theory (2007-)":

The Wheaton Recurrence

And here as Alexander Rook on the Syfy TV science fiction show "Dark Matter (2015-2017)":

Two vs Rook Dark Matter fanvid

Will looks like Dan O'Bannon in Dark Star in that last link.

The cast.

Then (199?):

Full TNG Cast Reunion Confirmed For ‘Destination Star Trek 3’

Now, 2 September 2018 (Jonathan Frakes was absent):

Star Trek: The Next Generation Cast Reunites with Patrick Stewart Over Dinner

It might be interesting... well, probably not, really... to hear the explanation of Data looking so much older.

Could be interesting to see if they could capture the magic of TNG again ,and maybe B-4 was given the ability to age by Dr. Soong

On Saturday 9 September 2018 Star Trek received the 2018 Governors Award from the Television Academy at the Creative Arts Emmys in recognition of its storied legacy in advancing science, society and culture.
