Honestly, having interviewed Billy Zane a few times over the years, hanging around with that dude would be pretty fun and “out there.” But as Brando? Man.

This is about Brando’s grandiose plans for his South Pacific island — home, compound, “resort hotel.”

Yes, there are laughs in this trailer. Zane does more than just “suggest” Marlon Brando in his posture, gestures and speech. Not quite a full-on “impersonation.”

The mercurial playfulness that flirted with comical megalomania is evident. And Richard Dreyfuss as the money man who just says “NO?” On the nose.

Heder as an architect trying to please a mad, egomaniacal dreamer? That scans.

Sept. 19, we see if this mad experiment comes off.
