I had this game back in the day. I remember the rather fetching box cover art, which was a twisted, weird clown face.
What a great cast as well, Christopher Lloyd, Ben Stein (the teacher from Ferris Bueller) and Tim Curry as the voice of the bad guy.
I’m sure Tijn will cover it in the development section, but I remember reading the game cost Virgin a lot of money, and it was a flop in terms of sales.
Also, Toonstruck was either half a game because the full plan was too expensive to complete, or work was started on a sequel.
