The story goes (according to Elfman himself) that they had a personal falling out, nothing to do with music or their relationship as director and composer, and were thereafter not on speaking terms for eighteen months.
During Mars Attacks pre-production, Elfman received a phone call from a producer asking him if he would consider speaking to Burton again. Elfman says he was on a plane the very next day, met up with Burton in a coffee shop, and they decided to never speak of their falling out again.
(I'm not kidding you - click the link - there really is an Elfman interview there conducted by SG staff. The mind boggles...! I love SG personally, but didn't really expect them to be conducting interviews with composers... It takes all sorts I guess!)
