But I think Kiss Kiss, Bang Bang really got that thing where, if a movie reads really funny and then has some dramatic or violent or sinister stuff in it, you can't forget that primarily it has to be even funnier than you read it or that other stuff doesn't work.

With a terrible script you hustle and try to make it better. But with a good script it can be trouble because you rest on your laurels, so to speak, you think it's going to translate easily.

When you have a good script you're almost in more trouble than when you have a terrible script.

Robert Downey, Jr. Quotes
