Hate to say it but this movie's 5 minutes of fame have come and gone. I don't think we'll get any others. Not for a good while, at least. They might be trying really hard to avoid being hit with the licensing banhammer and that's why we've heard next to nill.
Yeah, the movie does seem to have faded. You'd think if there was demand for a bootleg Furiosa there would be demand for an officially licensed Max by HT or someone, but I guess the actor isn't that famous.
