On Sunday, Oct. 30, dedicated fans trudged out into the rain to "Entertainment Weekly"'s PopFest held at The Reef in Los Angeles. Panels and shows included the casts of "Teen Wolf," "Grey's Anatomy," "American Horror Story," "Scream Queens," "Fantastic Beasts and Where to Find Them," and performers such as Tove Lo and JoJo. It was an exciting day filled with behind-the-scenes secrets and genuine connection with fans.

"Fantastic Beasts and Where to Find Them"

Eddie Redmayne (Newt) and Katherine Waterston (Porpentina) took the PopFest main stage for the first event. They discussed their new film "Fantastic Beasts," coming out Nov. 18, and treated the audience to some never before seen clips. Of course, no one was allowed to record these previews because everyone needed to #keepthesecrets. When asked about what took some getting used to on set, Waterson admitted, "I was so embarrassed when I first picked up my wand. I was afraid to even lift it up because I felt goofy. I made them make my wand heavier just so it would feel more substantial." No judgement, Katharine. Most people aren't trained in wand holding. Apparently there's a technique to it?

"Teen Wolf"

Where do we start? The quirky and adorable cast members of "Teen Wolf" provided many humorous moments during their time on stage. First off, Tyler Posey (Scott) came on stage and proceeded to jump along all of the couches before sitting down in his seat. Later, the interviewer proposed a hilarious game of truth or dare in which Shelley Hennig (Malia) chugged an entire bottle of water, Cody Christian (Theo) announced his unexplained strange crush on Betty White, Tyler Posey hugged a fan and Khylin Rhambo (Mason) did a wonderful Samuel L. Jackson impression. These young actors had way too much fun on stage. Let's just say that sounds like a cast I want to be a part of.

"Scream Queens"/"American Horror Story"/"People vs. OJ"

To escape the rain outside many fans flocked indoors to the theater where stars such as Emma Roberts ("Scream Queens" – Chanel), Lea Michele ("Scream Queens" – Hester), Jamie Lee Curtis ("Scream Queens" – Cathy), Evan Peters ("AHS" – Tate) and Cuba Gooding Jr. ("People vs. OJ" – OJ Simpson) discussed their roles on their respective shows with their producer Ryan Murphy. After discussing where each of the shows are headed in the coming seasons, we heard from other characters about their roles. The funniest comment came from Cuba Gooding Jr. when discussing working on the set of "American Horror Story." He described walking into the iconic mansion, paused and stated, "Honestly, this is some of the scariest sh** I've ever done," which caused a roar of laughter from the audience. Surely walking through a haunted mansion full of creepy cast members isn't the most pleasant experience, so we totally understand where you're coming from, Cuba.

Side Note to those "American Horror Story" fans: Ryan Murphy announced exclusively at "EW" PopFest that he's going to release a "Murder House" and "Coven" crossover season. While it won't be the next season of "AHS," it's coming for sure, so get ready.

Comedy Improv All-Stars Showcase

While there were other panels and shows to see, we ended with the Comedy All Stars Improv showcase in the theater. It included popular faces such as D'Arcy Carden, Neil Casey, Adam Pally, Neil Flynn, Brian Huskey and more. The actors were given a story to work from and took it from there. It included skits of friends on a roadtrip joined by a talking bag of Doritos, a couple fighting over the fact that the wife read her husband's diary, a car insurance company that didn't cover corn field damage and two time travelling aliens pretending to rush a sorority called "Delta Glamour." The funniest part of the show? The two actors posing as sorority girls were asked what their names were and came up with Carbon Dioxide and Liquid Tiger. Maybe these types of names will start to catch on in the Greek Life world?

PopFest proved to be an exciting event where fans were able to interact with some of their favorite cast members from popular shows, and learn more about what happens behind-the-scenes. It was an entertaining day and "Entertainment Weekly" surely didn't disappoint.
