I just saw that Hollywood Reporter article and raced here to see if it had been posted, and as usual, jimbo has already got it covered
Well, Johnny's detractors *always* think he's overexposed, so that criticism is nothing new. With few exceptions (such as having no films out in 2008) he usually puts out about 2 films a year. There will be 2 this year, if Parnassus ends up being released. He also narrated a Doors documentary, which might be released soon. There will be at least 2 next year (Alice and The Rum Diary). Rango is scheduled for 2011. So, even if he is not that active right now, he still has a steady stream of films scheduled for release. He's not in danger of being someone like Jude Law, who I think I was just reading put out 6 films in one year a few years ago, but he will continue to have films released.
Alice is no doubt taking a long time because it's heavily animated *and* they're adding 3D. I'm disappointed (because of the delays it will cause DS) but not surprised that it's taking a long time. In contrast, The Rum Diary wrapped filming in June, and the director believes he will have it finished in Sept., which isn't surprising because it's just a straight drama without a lot of action or effects. So MB is right that films can take any amount of time.
I never saw the 2004 pilot, so this is the first that I've heard that it was campy. Maybe I'm glad that it wasn't picked up, then.
