An illustrator gets pulled into his drawing. I swear it's Brendan Fraiser, but I can't find any reference to it anywhere.
I think he's in his office because I'm sure I remember him sitting at a proper big drawing board and there's big office building windows and fluorescent lights.
In the story there's a river boat and piranhas and the really strange conversation about how the main character doesn't have a belly button because the illustrator wasn't allowed to draw her one, I think it was meant to be considered indecent or some such nonsense.
There might be a PI because I think I remember the door with frosted glass and the name being written backwards because it's being seen from inside the drawing.
Please help! I've been looking for this film for years :(

It's not Monkeybone. Everyone's told me that's it but it's not even close
