Once upon a time, Marvel Television was being overseen by Jeph Loeb and director Kevin Smith (Clerks, Mallrats, Jay & Silent Bob Strike Back) was hired to make a mature cartoon series focused on Howard The Duck. However, the project was ultimately trashed leading to Smith to focus on his Netflix cartoon series Masters of The Universe: Revelation.
Marvel Television was re-branded as Marvel TV Studios with Loeb exiting the company because Kevin Feige became Marvel’s chief creative officer giving him complete control over all divisions, including television and animation. The M.O.D.O.K. animated show using stop-motion was the only thing that really survived the mass cancellations of the Marvel television shows to make way for hard-canon stuff heading to Disney+ starting with WandaVision.
Smith revealed on his podcast Fatman Beyond that he asked to use Werewolf By Night (Marvel’s big werewolf character), but his request was denied by Jeph Loeb because Marvel Studios (the film division) had plans for the character. Back then, Marvel Television had to get approval to use certain characters that the film division was going to use.
“In my head, as I started building my season, I was like, ‘Alright, Episode 5, Werewolf By Night.’ The idea of our story was that Howard was trapped here and he was trying to get pages of the Darkhold, which would allow him to go back. There’s Howard as I’m laying it out and then I go into Jeph and told him what I wanted to do, and that’s when they said ‘You can’t use Werewolf By Night,’ and I asked why? They said the movie division was using him.”

Jack Russell aka Werewolf By Night has been seen in animation but there was once a live-action version that many people might not be aware of. He appeared in a deleted scene from Blade Trinity, however, as you can see below the scene was so bad (like the rest of the movie) it was abandoned. It invokes memories of the deleted scene from the original Blade, where director Stephen Norrington played Morbius The Living Vampire as a way to set him up as the villain of the sequel only for that scene to be cut (Sony Pictures owned the rights) and Guillermo del Toro going in another direction with Blade II.
It’ll be interesting to see what project Russell could end up showing up in as things like the Moon Knight series and Blade reboot are helping to introduce the horror corner of Marvel Comics to the Marvel Cinematic universe.
