That '70s Panel
Room 8
The seventies were a time of change for comics: Veteran creators were melding with new talent and new kinds of comics were emerging. Here's a discussion of those changing times with Marv Wolfman (Tomb of Dracula), Steve Leialoha (Warlock), Rick Hoberg (Star Wars), Richard Pini and Wendy Pini (Elfquest), moderator Mark Evanier (Scooby Doo), and others.

The Genius of Animation: Problem Solving in Character and Story
Room 23ABC
Did you know The Flintstones started out as a show about hillbillies? Frozen's Anna and Elsa didn't start out as sisters? So many of the cartoon characters and storylines you love went through lots of changes to become the versions you know. Panelists will examine some of your favorite movies and cartoon shorts with the artists responsible for creating/developing them, learn about fascinating bumps in the road, and how they got past them. Featuring Floyd Norman (Disney legend, animator and story artist, Sleeping Beauty, Jungle Book), Jane Baer (animator, Sleeping Beauty, Who Framed Roger Rabbit?), Nik Ranieri (character animator, Who Framed Roger Rabbit?, Beauty and the Beast), Ricardo Delgado (production designer, Atlantis; visual development artist, The Incredibles, Wall-E), Kathy Zielinski (lead animator, The Little Mermaid, Frozen), Aliki Theofilopoulos (supervising producer: Harvey Street Kids, storyboard artist/writer: Phineas and Ferb), Randy Haycock (character animator, The Lion King, Moana), Shadi Petosky (co-creator Danger & Eggs, executive producer: Twelve Forever), and Mindy Johnson (animation historian, author, Ink and Paint: The Women of Walt Disney's Animation). Moderated by Leslie Combemale (CinemaSiren.com, ASIFA: Hollywood).
