Thanks for reminding me about the 101 Dalmatians one.
I always think in animation, you have unlimited boundaries as far as action goes because hell, you just draw away. Do anything that's not even humanly impossible (like survive multiple blasts of dynamite by only having a black burnt face as a result).
I don't think it's impossible to convert to live action from animation but like you said, it's pretty difficult.
But you do make a good point about budget. I think these days, they kind of go hand in hand.
Speed Racer, the live action one, costs about $120 million for their budget (not how much they made in the box office) while
Up's budget was $175 million. I guess it all depenRAB on how much effort/CGI was put in to it, not to mention the whole production costs and those other tidbits.
Then again, there is the 2D style animation like
The Powerpuff Girls Movie (2002, $11 million) and
The Simpsons Movie (2007, $75 million). One of the differences between these two and others such as
Kung Fu Panda or
Wall-E other than animation tactics is likely the whole process of voice actors. Powerpuff Girls and Simpsons had at least majority of their respective voice cast while other animated films not based on the TV series or foreign shows (unless, however, it's based on an old show where many of its original voice actors have either passed away or retired) have to find and audition numerous actors and actresses with sound check and all. And then having to fly them in to do the recording and stuff...
I know not all live action/animation films are like this depending on how much is put in to the film in terms of effects, CGI stuff. There are movies, live action or not, whose budget go for at least $20 million (
Kick-Ass).
I don't know the whole technical stuff that could make the integration of CGI/Live Action that could be slightly cheaper or maybe around the same costs.
Garfield: $50 million
Alvin and the Chipmunks: $65 million
Who Framed Roger Rabbit: $70 million
Space Jam: $80 million
Somehow, I kinda expected it to be a little more expensive intertwining Live Action and CGI together but I guess with advanced technology, it's a bit easier as opposed if you did it with
Who Framed Roger Rabbit.
Cost effective wise, maybe it's a little easier to do the corabination of both. But the nurabers between the corabining of both live action/CGI, solely animation, and solely live action adaptation...depending on the effects and production stuff put in to, isn't too far off.
Anywho, here's a few sites that have links to the budget nurabers. Mostly "blockbuster" like films. Doesn't seem to list every single movie ever made.
