'Everwood' and 'Hey Dude' Casts to Reunite at the ATX TV Fest: Who Will Be There and How You Can Attend (and Participate!)

We have very exciting, exclusive news for those of you who grew up laughing and crying with "Everwood," The CW drama for the thinking teenager (and teenager at heart). Come June 5, the cast will reunite at the ATX Television Festival in Austin, Texas. If you want a taste of what's to come, check out this Twitter picture posted by Tom Amandes, whom you might remember as Dr. Harold Abbott, strictest doctor/dad ever. The caption reads: "Dear 'old' friends I've had the privilege to watch grow up!" Clearly, Amandes is way softer than Dr. Abbott, right?

And now, festival attendees will get to share in the excitement when piano prodigy Ephram (Gregory Smith) and his beloved girl next door, Amy Abbott (Emily VanCamp), get back together. The onscreen star-crossed crushers will be in Austin, along with Treat Williams, David Hudgins, Rina Mimoun, Chris Pratt, Amandes, Scott Wolf, Stephanie Niznik, Vivien Cardone, John Beasley, and Merrilyn Gann.

The game of "Where are they now?" is supereasy when it comes to the young stars of "Everwood." We all know that VanCamp has become a TV "it" girl on ABC's megahit drama "Revenge." And it's hard to believe that Smith, whose performance of piano prodigy/awkward fish out of water of Ephram Brown earned him "Breakout Star" status from Entertainment Weekly in 2003, is all grown up and hanging tough on "Rookie Blue."

And, of course there's Chris Pratt, of "Parks and Recreation," who has become Hollywood's cutest go-to goof. Pratt is busy offscreen as well. He and his wife, "Mom" star Anna Faris are the proud parents of a baby boy, Jack. And somehow he found time to get superhot. Pratt went off beer for six months and slimmed down (aka hunked up) for his role in "Guardians of the Galaxy." If you missed his selfie, now would be a good time to indulge and check it out.

"Our philosophy is that once you're a fan of a show, you're a fan for life. Because of that, reunions have become a major part of ATX Festival programming," ATX Television co-founders Caitlin McFarland and Emily Gipson told Yahoo TV. "We're excited to announce that Season 3's reunions will include 'Hey Dude,' a staple of our youth, and 'Everwood,' a series that captured — and continues to live in — the hearts of so many. We love bringing together casts and crews of shows that haven't seen each other in five, 10, even 20 years. Sometimes it's hard to tell who is more excited — the fans or the cast members."

It's also hard to tell whether "Everwood" fans or "Hey Dude" fans will be more excited. And that's because ATX is also hosting a reunion of the Nickelodeon show about life on a dude ranch. Tiger Beat pinup David Lascher will be there — yee! — along with fellow ranchers Alan Goodman, Lisa Melamed, Debrah Kalman, Kelly Brown, Geoffrey Coy, and David Brisbin. But the most exciting thing about the "Hey Dude" reunion will be hearing "Justified" showrunner Graham Yost talk about evolving from squeaky clean to super badass.

Yost told the Hollywood Reporter that the '80s hit was a big break: "My first big scripted job was 'Hey Dude' on Nickelodeon, and that was their first scripted show. I worked on the 65 episodes produced in two years. Just as a writer, we got to do all the classics. Have the boy and girl who say they don't like each other but really do, have them get handcuffed together, and someone loses the key. So, let's do that episode. Let's do the one where the middle-aged owner of the place gets hit on the head and thinks he's 15 years old again. Let's do that one. It was fun."

Watch a clip from "Hey Dude" and sing along to its catchy theme song: 

Sadly, Christine Taylor, who played Melody Hanson in "Dude" and went on to knock it out of the park as Marcia Brady in the "Brady Bunch" spoof movies, isn't on the list. But if you want to see what Mrs. Ben Stiller has been up to, we strongly suggest you check out "Arrested Development" on Netflix.

And, if you think you'd like to go the way of Yost and write for TV, then check out the ATX TV Festival website. You'll find details about participating shows ("Bates Motel," "Rectify") and panelists (Amy Sherman Palladino, Paul Scheer, Scott Porter, more)— and how to attend. The festival hosts a pitch competition and the winner gets a meeting with the judges, who include producer/director David Semel ("Homeland") and Julie Plec ("The Vampire Diaries") among others.
