It’s difficult to believe13 Going on 30was released all the way back in 2004.

The lesson there is to just be yourself."

“This is one of the best groups of people that most of us have ever worked with.

Speaking about the role toThe Fandom Files, Marquette laughed, “Oh my gosh.

It’s so much fun for me.

Christa B Allen then and now

It’s so funny!”

That show has been the most incredible experience.

So much fun.”

Sean Marquette then and now

“[It] was a dream job for me at the time.

I met so many incredibly warm people whom I’m still close with today.

I think I also loved getting to be part of such a sweet, lighthearted story.

Alexandra Kyle then and now

It was a complete 180,” she shared.

The young actor even appeared in 2002’s Tobey Maguire-ledSpider-Manas “Boy on Tram.”

Black has kind of fallen off the radar in the years since.

Alex Black then and now

Maybe he just went the way of Seth Powers and got lured off by a particularly attractive basketball.

Or maybe he’s just living a normal life somewhere.

Still, we wouldn’t mind seeing him return to the small screen.

Ashley Benson then and now

Maybe in aNed’s Declassifiedreunion?

“I’ve definitely matured a lot!

Pretty Little Liarswas clearly a dream for Benson.

Brie Larson then and now

A lot of my friends are very normal with normal jobs… She explained, “The tough stuff teaches you a lot about yourself.

I can tap into those moments of rejection and pain, and put them into a film.

I’m grateful those things happened.”

Brittany Curran then and now

She may be hugely successful these days, but Larson isn’t counting her chickens.

I don’t want to get swept up in lipstick or whatever the hell.”

But Brittany Curran took a more… magical route.

Megan Lusk then and now

The young actress had a starring role onThe Magicians, a show that’s a sort ofHarry Potterfor adults.

Thankfully, they appreciated her gumption.

“It went really well!

Julia Roth then and now

It’s funny because I play b****esa lotin movies and stuff.

So to play this innocent and naive character has been really fun for me.”

Her final role to date was in the hit showWithout A Tracein 2005.

Renee Olstead then and now

Since then…nada.

Similar to Alex Black, Lusk appears to have stepped out of the spotlight almost completely.

Likewise, the actress is a vocal fan of Netflix’sGrace and Frankie.

Gia Mantegna then and now

Movie-wise, Olstead played Jess in the hit horror filmUnfriended.

When something terrible happens, our knee-jerk reaction now is to pull our phones out."

Remember that they have a dream, just like you do, and be supportive."

Sara Swain then and now

Most notably, Gia Mantegna appeared as the brilliantly monikered Devin Levin in hit sitcomThe Middle.

Unfortunately for fans,the serieswrapped up its second and final season in 2011.

Beaudoin’s career hasn’t exactly been stacked, as it would appear she chooses projects wisely.
