The movie Titanic was rendered, in no small part, with Amigas running AREXX to control the per-frame rendering and result submission. Many Amiga applications included an AREXX interface port (I used the one in the terminal emulator for automated dialing).
PC-DOS 6 (The IBM release, that also included CDROM drivers, and came on CD), had an IBM port of mainframe REXX, as well.
