'Beverly Hills, 90210' veteran Gabrielle Carteris is returning to TV in several upcoming episodes of 'The Event.' Yep, Andrea Zuckerman will be playing an alien.

According to TV Guide, Carteris will play Diane, an old friend of Michael Buchanan. When Michael and Sophia decide to hunt down Thomas in the March 21 episode, Michael leaves his kids in the care of Diane.

Carteris' upcoming turn on 'The Event' got the old nostalgia wheel turning. With Carteris on 'The Event' and Larisa Oleynik of 'Alex Mack' fame on 'Hawaii Five-0,' it's like a 1990s renaissance! Here are five other '90s TV stars we want -- no, need -- back on our TV screens for a spell.

Superstar Molly Shannon will reportedly play Sue Sylvester's (Jane Lynch) new pill-popping nemesis on the award-winning Fox comedy 'Glee.' The role -- astronomy teacher/badminton coach Brenda Castle -- is said to be recurring, and will make its debut in time for May sweeps. As if Gleeks needed more to sing about. [Ausiello Files]

More casting news after the jump.

How good are you at spotting someone's true age? There's been a few times I've caught myself wondering how old that actor really is on TV, when they're playing someone my age and look ten years older. Do I really look that good? Then again, I've seen the opposite and thought, "damn, I am an old decrepit fart." In any case, I'll pull up IMDb and usually find myself in shock of how young/old the actor on-screen really is.

The whole actor-to-character age ratio thing got me curious, so I did a little research (with the help of some of the TV Squad team) and made a list of some of the more extreme and well-known (or, maybe to some, not-so-well-known) examples. By the way, we didn't include actors who played flashback scenes of their characters for short periods of time, as there are more of those than we have room for.

(S04E11) ABC brought George Lopez back out of mothballs this week, so there was no 8:00 recap show. Instead, Tom and Samantha ran through the performances quickly at the beginning of the show. The best part of that was seeing Ian's reaction to the judge's comments last night. Much like many of the readers here, Ian didn't really understand where they were coming from.

It's a good point, and something that seems to happen every season. For whatever reason, the judges get a burr under their saddle and just go after one of the better contestants, while soft-pedaling some of the lesser routines. His best course of action is to move along and know that he's in good company.
