KABLAM WIKI ADMIN NOTE: This is not the Mark Marek who runs the gore site.
"His artistic input became a real turning point for the show."
– Chris Viscardi, co-creator of KaBlam! interviewed in Not Just Cartoons: Nicktoons!
Graduating from the University of Texas at Austin in 1978, Marek would later send a demo tape of rough animations to some art directors he was familiar with at Nickelodeon. He would then get a callback and was asked to animate for KaBlam!. Nickelodeon’s then-Senior Vice President of Production, Kevin Kay, told a local New Jersey newspaper that "Mark has a unique talent. We're very anti-'house style,' and his work looks very different from everything else that is on our air."
Marek began operating his independent animation studio Crank! It! Out! Inc. in 1995, animating the segments by himself to start, and then bringing on another animator. By the time KaBlam! came to an end, he had a team of 14 people. The five minutes of Henry and June for each episode took about three weeks to complete. Show creators Robert Mittenthal, Will McRobb and Chris Viscardi didn’t give Marek a lot of direction, except that Henry should look unkempt, as if he had just gotten out of bed. June was a little more organized, and Henry would be the one who was always catching up to her (Marek filled in the blanks from there).
Marek also did voices for characters on the Henry and June segments, credited as Dr. Ferdinand Blem in the Season 1 episode "Resistance is Futile" and did other small voicing parts. On the Season 4 episode/KaBlam! series finale "Just Chillin'," he and Crank! It! Out! Inc. presented a traditional animation segment titled Dave, Son of Hercules, a sequel to Marek's comic book "Hercules: Amongst the North Americans."
After his time at Nickelodeon, Marek created a short film "Yuck Yuck Goose and His Sidekick, His Butt" for MTV2's adult sketch comedy series Wonder Showzen in 2005. From 2010 to 2013, he was a producer of the Cartoon Network animated series MAD, reuniting with Julia McIlvaine (voice of June) who portrayed various characters. Marek has been an animation supervisor at Warner Bros. Animation since March 2010. His latest work in animation is co-producer of Yabba-Dabba Dinosaurs (a spinoff of The Flintstones), released on HBO Max in late September 2021.
