Hollywood without any doubt, it is language of high level as C, easy, fast and you can compilate your projects to several systems of Amiga, besides of Windows and MAC OS.
Hollywood is good, but nothing like C in speed, syntax or efficiency. And while it may run fast on ghz level machines, it's painfully slow on classics so it depends on what platform he is targetting.
He did mention MUI and Intuition, neither of which can be used in Hollywood (correct me if I'm wrong). As far as I know Scui is the only usable GUI toolkit.
