Turns out Heath is familiar with one of his bosses on the new Batman 2 film.
Producer Charles Roven, who worked with Heath on the Terry Gilliam film, Brothers Grimm,
is also a producer of the Batman films. Heath seems to keep friendly with people he has
worked with before; they find him professional and affable and don't mind working with
him again.
When there's nightmare actors like Val Kilmer (people only work with him once), it makes you
respect actors like Heath even more.
