Cartoon and live action mash up ideas

There should be a movie set in old Hollywood, but there is a part of it where like real cartoons live. They could call it Toon Town or whatever.

Then there's a murder/mystery aspect to it where some Hollywood icon who loves toons actually doesn't, but there's also a love triangle potential where he's sleeping with this smoking hot toon, or maybe just playing patty-cake with each other and there's this whole misunderstanding.

Then in his will the icon could leave Toon Town to the toons, but nobody can find the will. And the whole time there's this semi-lovable, semi-hateable character named Roger who is an animal (like a rabbit or a squirrel or something), and it turns out HE'S married to the smoking hot toon.

And the villain can be a judge who goes around torturing and violently murdering cartoons in a vat of acid. But the twist at the end is that he, himself, is actually also a cartoon who killed the brother of the detective who was hired to sort it all out in the first place.

They could call it something like "Someone Framed Roger Squirrel" or something like that.
