Hollywood is only suitable for making 24-bit video and, as such, it is typically too slow on the classic Amigas. It works great on PowerPC systems running MorphOS or AmigaOS 4 or Pentiums running AROS. Also, it includes cross-compilers with any version of Hollywood that you buy so you can create fast games for any of those platforms even if you only have one of them. (I'd recommend having testers anyway, however.)
