True. I've read two different screenplays and they're both shit.
I had the good fortune to work with Morgan Freeman once; he's got a model of Rama in his production company's foyer. I asked him when the movie was coming out and he said "as soon as we get a decent script."
it's been said that the reason Tom Hanks owns the rights to Stranger in a Strange Land is to prevent any producer from ever fucking it up.
